+
+
+## Introduction
+BaconQrCode is a port of QR code portion of the ZXing library. It currently
+only features the encoder part, but could later receive the decoder part as
+well.
+
+As the Reed Solomon codec implementation of the ZXing library performs quite
+slow in PHP, it was exchanged with the implementation by Phil Karn.
+
+
+## Example usage
+```php
+use BaconQrCode\Renderer\ImageRenderer;
+use BaconQrCode\Renderer\Image\ImagickImageBackEnd;
+use BaconQrCode\Renderer\RendererStyle\RendererStyle;
+use BaconQrCode\Writer;
+
+$renderer = new ImageRenderer(
+    new RendererStyle(400),
+    new ImagickImageBackEnd()
+);
+$writer = new Writer($renderer);
+$writer->writeFile('Hello World!', 'qrcode.png');
+```
+
+## Available image renderer back ends
+BaconQrCode comes with multiple back ends for rendering images. Currently included are the following:
+
+- `ImagickImageBackEnd`: renders raster images using the Imagick library
+- `SvgImageBackEnd`: renders SVG files using XMLWriter
+- `EpsImageBackEnd`: renders EPS files

+
+It is a well known fact that PHP is missing a basic enum type, ignoring the rather incomplete `SplEnum` implementation
+which is only available as a PECL extension. There are also quite a few other userland enum implementations around,
+but all of them have one or another compromise. This library tries to close that gap as far as PHP allows it to.
+
+## Usage
+
+### Basics
+
+At its core, there is the `DASPRiD\Enum\AbstractEnum` class, which by default will work with constants like any other
+enum implementation you might know. The first clear difference is that you should define all the constants as protected
+(so nobody outside your class can read them but the `AbstractEnum` can still do so). The other even mightier difference
+is that, for simple enums, the value of the constant doesn't matter at all. Let's have a look at a simple example:
+
+```php
+use DASPRiD\Enum\AbstractEnum;
+
+/**
+ * @method static self MONDAY()
+ * @method static self TUESDAY()
+ * @method static self WEDNESDAY()
+ * @method static self THURSDAY()
+ * @method static self FRIDAY()
+ * @method static self SATURDAY()
+ * @method static self SUNDAY()
+ */
+final class WeekDay extends AbstractEnum
+{
+    protected const MONDAY = null;
+    protected const TUESDAY = null;
+    protected const WEDNESDAY = null;
+    protected const THURSDAY = null;
+    protected const FRIDAY = null;
+    protected const SATURDAY = null;
+    protected const SUNDAY = null;
+}
+```
+
+If you need to provide constants for either internal use or public use, you can mark them as either private or public,
+in which case they will be ignored by the enum, which only considers protected constants as valid values. As you can
+see, we specifically defined the generated magic methods in a class level doc block, so anyone using this class will
+automatically have proper auto-completion in their IDE. Now since you have defined the enum, you can simply use it like
+that:
+
+```php
+function tellItLikeItIs(WeekDay $weekDay)
+{
+    switch ($weekDay) {
+        case WeekDay::MONDAY():
+            echo 'Mondays are bad.';
+            break;
+
+        case WeekDay::FRIDAY():
+            echo 'Fridays are better.';
+            break;
+
+        case WeekDay::SATURDAY():
+        case WeekDay::SUNDAY():
+            echo 'Weekends are best.';
+            break;
+
+        default:
+            echo 'Midweek days are so-so.';
+    }
+}
+
+tellItLikeItIs(WeekDay::MONDAY());
+tellItLikeItIs(WeekDay::WEDNESDAY());
+tellItLikeItIs(WeekDay::FRIDAY());
+tellItLikeItIs(WeekDay::SATURDAY());
+tellItLikeItIs(WeekDay::SUNDAY());
+```
+
+### More complex example
+
+Of course, all enums are singletons, which are not cloneable or serializable. Thus you can be sure that there is always
+just one instance of the same type. Of course, the values of constants are not completely useless, let's have a look at
+a more complex example:
+
+```php
+use DASPRiD\Enum\AbstractEnum;
+

+GPL Cooperation Commitment
+Version 1.0
+
+Before filing or continuing to prosecute any legal proceeding or claim
+(other than a Defensive Action) arising from termination of a Covered
+License, we commit to extend to the person or entity ('you') accused
+of violating the Covered License the following provisions regarding
+cure and reinstatement, taken from GPL version 3. As used here, the
+term 'this License' refers to the specific Covered License being
+enforced.
+
+    However, if you cease all violation of this License, then your
+    license from a particular copyright holder is reinstated (a)
+    provisionally, unless and until the copyright holder explicitly
+    and finally terminates your license, and (b) permanently, if the
+    copyright holder fails to notify you of the violation by some
+    reasonable means prior to 60 days after the cessation.
+
+    Moreover, your license from a particular copyright holder is
+    reinstated permanently if the copyright holder notifies you of the
+    violation by some reasonable means, this is the first time you
+    have received notice of violation of this License (for any work)
+    from that copyright holder, and you cure the violation prior to 30
+    days after your receipt of the notice.
+
+We intend this Commitment to be irrevocable, and binding and
+enforceable against us and assignees of or successors to our
+copyrights.
+
+Definitions
+
+'Covered License' means the GNU General Public License, version 2
+(GPLv2), the GNU Lesser General Public License, version 2.1

+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+- Compatible with PHP 5.5 and later, including PHP 8.4
+- Namespaced to prevent name clashes
+- Much more!
+
+## Why you might need it
+Many PHP developers need to send email from their code. The only PHP function that supports this directly is [`mail()`](https://www.php.net/manual/en/function.mail.php). However, it does not provide any assistance for making use of popular features such as authentication, HTML messages, and attachments.
+
+Formatting email correctly is surprisingly difficult. There are myriad overlapping (and conflicting) standards, requiring tight adherence to horribly complicated formatting and encoding rules – the vast majority of code that you'll find online that uses the `mail()` function directly is just plain wrong, if not unsafe!
+
+The PHP `mail()` function usually sends via a local mail server, typically fronted by a `sendmail` binary on Linux, BSD, and macOS platforms, however, Windows usually doesn't include a local mail server; PHPMailer's integrated SMTP client allows email sending on all platforms without needing a local mail server. Be aware though, that the `mail()` function should be avoided when possible; it's both faster and [safer](https://exploitbox.io/paper/Pwning-PHP-Mail-Function-For-Fun-And-RCE.html) to use SMTP to localhost.
+
+*Please* don't be tempted to do it yourself – if you don't use PHPMailer, there are many other excellent libraries that
+you should look at before rolling your own. Try [Symfony Mailer](https://symfony.com/doc/current/mailer.html), [Laminas/Mail](https://docs.laminas.dev/laminas-mail/), [ZetaComponents](https://github.com/zetacomponents/Mail), etc.
+
+## License
+This software is distributed under the [LGPL 2.1](https://www.gnu.org/licenses/old-licenses/lgpl-2.1.html) license, along with the [GPL Cooperation Commitment](https://gplcc.github.io/gplcc/). Please read [LICENSE](https://github.com/PHPMailer/PHPMailer/blob/master/LICENSE) for information on the software availability and distribution.
+
+## Installation & loading
+PHPMailer is available on [Packagist](https://packagist.org/packages/phpmailer/phpmailer) (using semantic versioning), and installation via [Composer](https://getcomposer.org) is the recommended way to install PHPMailer. Just add this line to your `composer.json` file:
+
+```json
+"phpmailer/phpmailer": "^6.10.0"
+```
+
+or run
+
+```sh
+composer require phpmailer/phpmailer
+```
+
+Note that the `vendor` folder and the `vendor/autoload.php` script are generated by Composer; they are not part of PHPMailer.
+
+If you want to use XOAUTH2 authentication, you will also need to add a dependency on the `league/oauth2-client` and appropriate service adapters package in your `composer.json`, or take a look at
+by @decomplexity's [SendOauth2 wrapper](https://github.com/decomplexity/SendOauth2), especially if you're using Microsoft services.
+
+Alternatively, if you're not using Composer, you
+can [download PHPMailer as a zip file](https://github.com/PHPMailer/PHPMailer/archive/master.zip), (note that docs and examples are not included in the zip file), then copy the contents of the PHPMailer folder into one of the `include_path` directories specified in your PHP configuration and load each class file manually:
+
+```php
+<?php
+use PHPMailer\PHPMailer\PHPMailer;
+use PHPMailer\PHPMailer\Exception;
+
+require 'path/to/PHPMailer/src/Exception.php';
+require 'path/to/PHPMailer/src/PHPMailer.php';
+require 'path/to/PHPMailer/src/SMTP.php';
+```
+
+If you're not using the `SMTP` class explicitly (you're probably not), you don't need a `use` line for it. Even if you're not using exceptions, you do still need to load the `Exception` class as it is used internally.
+
+## Legacy versions
+PHPMailer 5.2 (which is compatible with PHP 5.0 — 7.0) is no longer supported, even for security updates. You will find the latest version of 5.2 in the [5.2-stable branch](https://github.com/PHPMailer/PHPMailer/tree/5.2-stable). If you're using PHP 5.5 or later (which you should be), switch to the 6.x releases.
+
+### Upgrading from 5.2
+The biggest changes are that source files are now in the `src/` folder, and PHPMailer now declares the namespace `PHPMailer\PHPMailer`. This has several important effects – [read the upgrade guide](https://github.com/PHPMailer/PHPMailer/tree/master/UPGRADING.md) for more details.
+
+### Minimal installation
+While installing the entire package manually or with Composer is simple, convenient, and reliable, you may want to include only vital files in your project. At the very least you will need [src/PHPMailer.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/PHPMailer.php). If you're using SMTP, you'll need [src/SMTP.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/SMTP.php), and if you're using POP-before SMTP (*very* unlikely!), you'll need [src/POP3.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/POP3.php). You can skip the [language](https://github.com/PHPMailer/PHPMailer/tree/master/language/) folder if you're not showing errors to users and can make do with English-only errors. If you're using XOAUTH2 you will need [src/OAuth.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/OAuth.php) as well as the Composer dependencies for the services you wish to authenticate with. Really, it's much easier to use Composer!
+
+## A Simple Example
+
+```php
+<?php
+//Import PHPMailer classes into the global namespace
+//These must be at the top of your script, not inside a function
+use PHPMailer\PHPMailer\PHPMailer;
+use PHPMailer\PHPMailer\SMTP;
+use PHPMailer\PHPMailer\Exception;
+
+//Load Composer's autoloader (created by composer, not included with PHPMailer)
+require 'vendor/autoload.php';
+
+//Create an instance; passing `true` enables exceptions
+$mail = new PHPMailer(true);
+
+try {
+    //Server settings
+    $mail->SMTPDebug = SMTP::DEBUG_SERVER;                      //Enable verbose debug output
+    $mail->isSMTP();                                            //Send using SMTP
+    $mail->Host       = 'smtp.example.com';                     //Set the SMTP server to send through
+    $mail->SMTPAuth   = true;                                   //Enable SMTP authentication
+    $mail->Username   = 'user@example.com';                     //SMTP username
+    $mail->Password   = 'secret';                               //SMTP password
+    $mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS;            //Enable implicit TLS encryption
+    $mail->Port       = 465;                                    //TCP port to connect to; use 587 if you have set `SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS`
+
+    //Recipients
+    $mail->setFrom('from@example.com', 'Mailer');
+    $mail->addAddress('joe@example.net', 'Joe User');     //Add a recipient
+    $mail->addAddress('ellen@example.com');               //Name is optional
+    $mail->addReplyTo('info@example.com', 'Information');
+    $mail->addCC('cc@example.com');
+    $mail->addBCC('bcc@example.com');
+
+    //Attachments
+    $mail->addAttachment('/var/tmp/file.tar.gz');         //Add attachments
+    $mail->addAttachment('/tmp/image.jpg', 'new.jpg');    //Optional name
+
+    //Content
+    $mail->isHTML(true);                                  //Set email format to HTML
+    $mail->Subject = 'Here is the subject';
+    $mail->Body    = 'This is the HTML message body <b>in bold!</b>';
+    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
+
+    $mail->send();
+    echo 'Message has been sent';
+} catch (Exception $e) {
+    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
+}
+```
+
+You'll find plenty to play with in the [examples](https://github.com/PHPMailer/PHPMailer/tree/master/examples) folder, which covers many common scenarios including sending through Gmail, building contact forms, sending to mailing lists, and more.
+
+If you are re-using the instance (e.g. when sending to a mailing list), you may need to clear the recipient list to avoid sending duplicate messages. See [the mailing list example](https://github.com/PHPMailer/PHPMailer/blob/master/examples/mailing_list.phps) for further guidance.
+
+That's it. You should now be ready to use PHPMailer!
+
+## Localization
+PHPMailer defaults to English, but in the [language](https://github.com/PHPMailer/PHPMailer/tree/master/language/) folder, you'll find many translations for PHPMailer error messages that you may encounter. Their filenames contain [ISO 639-1](https://en.wikipedia.org/wiki/ISO_639-1) language code for the translations, for example `fr` for French. To specify a language, you need to tell PHPMailer which one to use, like this:
+
+```php
+//To load the French version
+$mail->setLanguage('fr', '/optional/path/to/language/directory/');
+```
+
+We welcome corrections and new languages – if you're looking for corrections, run the [Language/TranslationCompletenessTest.php](https://github.com/PHPMailer/PHPMailer/blob/master/test/Language/TranslationCompletenessTest.php) script in the tests folder and it will show any missing translations.
+
+## Documentation
+Start reading at the [GitHub wiki](https://github.com/PHPMailer/PHPMailer/wiki). If you're having trouble, head for [the troubleshooting guide](https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting) as it's frequently updated.
+
+Examples of how to use PHPMailer for common scenarios can be found in the [examples](https://github.com/PHPMailer/PHPMailer/tree/master/examples) folder. If you're looking for a good starting point, we recommend you start with [the Gmail example](https://github.com/PHPMailer/PHPMailer/tree/master/examples/gmail.phps).
+
+To reduce PHPMailer's deployed code footprint, examples are not included if you load PHPMailer via Composer or via [GitHub's zip file download](https://github.com/PHPMailer/PHPMailer/archive/master.zip), so you'll need to either clone the git repository or use the above links to get to the examples directly.
+
+Complete generated API documentation is [available online](https://phpmailer.github.io/PHPMailer/).
+
+You can generate complete API-level documentation by running `phpdoc` in the top-level folder, and documentation will appear in the `docs` folder, though you'll need to have [PHPDocumentor](https://www.phpdoc.org) installed. You may find [the unit tests](https://github.com/PHPMailer/PHPMailer/blob/master/test/PHPMailer/PHPMailerTest.php) a good reference for how to do various operations such as encryption.
+
+If the documentation doesn't cover what you need, search the [many questions on Stack Overflow](https://stackoverflow.com/questions/tagged/phpmailer), and before you ask a question about "SMTP Error: Could not connect to SMTP host.", [read the troubleshooting guide](https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting).
+
+## Tests
+[PHPMailer tests](https://github.com/PHPMailer/PHPMailer/tree/master/test/) use PHPUnit 9, with [a polyfill](https://github.com/Yoast/PHPUnit-Polyfills) to let 9-style tests run on older PHPUnit and PHP versions.
+

+## History
+- PHPMailer was originally written in 2001 by Brent R. Matzelle as a [SourceForge project](https://sourceforge.net/projects/phpmailer/).
+- [Marcus Bointon](https://github.com/Synchro) (`coolbru` on SF) and Andy Prevost (`codeworxtech`) took over the project in 2004.

+# Security notices relating to PHPMailer
+
+Please disclose any security issues or vulnerabilities found through [Tidelift's coordinated disclosure system](https://tidelift.com/security) or to the maintainers privately.
+
+PHPMailer 6.4.1 and earlier contain a vulnerability that can result in untrusted code being called (if such code is injected into the host project's scope by other means). If the `$patternselect` parameter to `validateAddress()` is set to `'php'` (the default, defined by `PHPMailer::$validator`), and the global namespace contains a function called `php`, it will be called in preference to the built-in validator of the same name. Mitigated in PHPMailer 6.5.0 by denying the use of simple strings as validator function names. Recorded as [CVE-2021-3603](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2021-3603). Reported by [Vikrant Singh Chauhan](mailto:vi@hackberry.xyz) via [huntr.dev](https://www.huntr.dev/).
+
+PHPMailer versions 6.4.1 and earlier contain a possible remote code execution vulnerability through the `$lang_path` parameter of the `setLanguage()` method. If the `$lang_path` parameter is passed unfiltered from user input, it can be set to [a UNC path](https://docs.microsoft.com/en-us/dotnet/standard/io/file-path-formats#unc-paths), and if an attacker is also able to persuade the server to load a file from that UNC path, a script file under their control may be executed. This vulnerability only applies to systems that resolve UNC paths, typically only Microsoft Windows.
+PHPMailer 6.5.0 mitigates this by no longer treating translation files as PHP code, but by parsing their text content directly. This approach avoids the possibility of executing unknown code while retaining backward compatibility. This isn't ideal, so the current translation format is deprecated and will be replaced in the next major release. Recorded as [CVE-2021-34551](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2021-34551). Reported by [Jilin Diting Information Technology Co., Ltd](https://listensec.com) via Tidelift.
+
+PHPMailer versions between 6.1.8 and 6.4.0 contain a regression of the earlier CVE-2018-19296 object injection vulnerability as a result of [a fix for Windows UNC paths in 6.1.8](https://github.com/PHPMailer/PHPMailer/commit/e2e07a355ee8ff36aba21d0242c5950c56e4c6f9). Recorded as [CVE-2020-36326](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-36326). Reported by Fariskhi Vidyan via Tidelift. 6.4.1 fixes this issue, and also enforces stricter checks for URL schemes in local path contexts.
+
+PHPMailer versions 6.1.5 and earlier contain an output escaping bug that occurs in `Content-Type` and `Content-Disposition` when filenames passed into `addAttachment` and other methods that accept attachment names contain double quote characters, in contravention of RFC822 3.4.1. No specific vulnerability has been found relating to this, but it could allow file attachments to bypass attachment filters that are based on matching filename extensions. Recorded as [CVE-2020-13625](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-13625). Reported by Elar Lang of Clarified Security.
+
+PHPMailer versions prior to 6.0.6 and 5.2.27 are vulnerable to an object injection attack by passing `phar://` paths into `addAttachment()` and other functions that may receive unfiltered local paths, possibly leading to RCE. Recorded as [CVE-2018-19296](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2018-19296). See [this article](https://knasmueller.net/5-answers-about-php-phar-exploitation) for more info on this type of vulnerability. Mitigated by blocking the use of paths containing URL-protocol style prefixes such as `phar://`. Reported by Sehun Oh of cyberone.kr.
+
+PHPMailer versions prior to 5.2.24 (released July 26th 2017) have an XSS vulnerability in one of the code examples, [CVE-2017-11503](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2017-11503). The `code_generator.phps` example did not filter user input prior to output. This file is distributed with a `.phps` extension, so it is not normally executable unless it is explicitly renamed, and the file is not included when PHPMailer is loaded through composer, so it is safe by default. There was also an undisclosed potential XSS vulnerability in the default exception handler (unused by default). Patches for both issues kindly provided by Patrick Monnerat of the Fedora Project.
+
+PHPMailer versions prior to 5.2.22 (released January 9th 2017) have a local file disclosure vulnerability, [CVE-2017-5223](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2017-5223). If content passed into `msgHTML()` is sourced from unfiltered user input, relative paths can map to absolute local file paths and added as attachments. Also note that `addAttachment` (just like `file_get_contents`, `passthru`, `unlink`, etc) should not be passed user-sourced params either! Reported by Yongxiang Li of Asiasecurity.
+
+PHPMailer versions prior to 5.2.20 (released December 28th 2016) are vulnerable to [CVE-2016-10045](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-10045) a remote code execution vulnerability, responsibly reported by [Dawid Golunski](https://legalhackers.com/advisories/PHPMailer-Exploit-Remote-Code-Exec-CVE-2016-10045-Vuln-Patch-Bypass.html), and patched by Paul Buonopane (@Zenexer).
+
+PHPMailer versions prior to 5.2.18 (released December 2016) are vulnerable to [CVE-2016-10033](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-10033) a remote code execution vulnerability, responsibly reported by [Dawid Golunski](https://legalhackers.com/advisories/PHPMailer-Exploit-Remote-Code-Exec-CVE-2016-10033-Vuln.html).
+
+PHPMailer versions prior to 5.2.14 (released November 2015) are vulnerable to [CVE-2015-8476](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2015-8476) an SMTP CRLF injection bug permitting arbitrary message sending.
+
+PHPMailer versions prior to 5.2.10 (released May 2015) are vulnerable to [CVE-2008-5619](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2008-5619), a remote code execution vulnerability in the bundled html2text library. This file was removed in 5.2.10, so if you are using a version prior to that and make use of the html2text function, it's vitally important that you upgrade and remove this file.
+
+PHPMailer versions prior to 2.0.7 and 2.2.1 are vulnerable to [CVE-2012-0796](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2012-0796), an email header injection attack.
+
+Joomla 1.6.0 uses PHPMailer in an unsafe way, allowing it to reveal local file paths, reported in [CVE-2011-3747](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2011-3747).
+
+PHPMailer didn't sanitise the `$lang_path` parameter in `SetLanguage`. This wasn't a problem in itself, but some apps (PHPClassifieds, ATutor) also failed to sanitise user-provided parameters passed to it, permitting semi-arbitrary local file inclusion, reported in [CVE-2010-4914](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2010-4914), [CVE-2007-2021](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2007-2021) and [CVE-2006-5734](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2006-5734).
+
+PHPMailer 1.7.2 and earlier contained a possible DDoS vulnerability reported in [CVE-2005-1807](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2005-1807).
+
+PHPMailer 1.7 and earlier (June 2003) have a possible vulnerability in the `SendmailSend` method where shell commands may not be sanitised. Reported in [CVE-2007-3215](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2007-3215).

+# A short history of UTF-8 in email
+
+## Background
+
+For most of its existence, SMTP has been a 7-bit channel, only supporting US-ASCII characters. This has been a problem for many languages, especially those that use non-Latin scripts, and has led to the development of various workarounds.
+
+The first major improvement, introduced in 1994 in [RFC 1652](https://www.rfc-editor.org/rfc/rfc1652) and extended in 2011 in [RFC 6152](https://www.rfc-editor.org/rfc/rfc6152), was the addition of the `8BITMIME` SMTP extension, which allowed raw 8-bit data to be included in message bodies sent over SMTP.
+This allowed the message *contents* to contain 8-bit data, including things like UTF-8 text, even though the SMTP protocol itself was still firmly 7-bit. This worked by having the server switch to 8-bit after the headers, and then back to 7-bit after the completion of a `DATA` command.
+
+From 1996, messages could support [RFC 2047 encoding](https://www.rfc-editor.org/rfc/rfc2047), which permitted inserting characters from any character set into header *values* (but not names), but only by encoding them in somewhat unreadable ways to allow them to survive passage through a 7-bit channel. An example with a subject of "Schrödinger's cat" would be:
+
+```
+Subject: =?utf-8?Q=Schr=C3=B6dinger=92s_Cat?=
+```
+
+Here the accented `ö` is encoded as `=C3=B6`, which is the UTF-8 encoding of the 2-byte character, and the whole thing is wrapped in `=?utf-8?Q?` to indicate that it uses the UTF-8 charset and `quoted-printable` encoding. This is a bit of a hack, and not very human-friendly, but it works.
+
+Similarly, 8-bit message bodies could be encoded using the same `quoted-printable` and `base64` content transfer encoding (CTE) schemes, which preserved the 8-bit content while encoding it in a format that could survive transmission through a 7-bit channel.
+
+Domain names were originally also stuck in a 7-bit world, actually even more constrained to only a subset of the US-ASCII character set. But of course, many people want to have domains in their own language/script. Internationalized domain name (IDN) permitted this, using yet another complex encoding scheme called punycode, defined for domain names in 2003 in [RFC 3492](https://www.rfc-editor.org/rfc/rfc3492). This finally allowed the domain part (after the `@`) of email addresses to contain UTF-8, though it was actually an illusion preserved by email client applications. For example, an address of
+`user@café.example.com` translates to
+`user@xn--caf-dma.example.com` in punycode, rendering it mostly unreadable, but 7-bit friendly, and remaining compatible with email clients that don't know about IDN.
+
+The one remaining part of email that could not handle UTF-8 is the local part of email addresses (the part before the `@`).
+
+I've only mentioned UTF-8 here, but most of these approaches also allowed other character sets that were popular, such as [the ISO-8859 family](https://en.wikipedia.org/wiki/ISO/IEC_8859). However, UTF-8 solves so many problems that these other character sets are gradually falling out of favour, as UTF-8 can support all languages.
+
+This patchwork of overlapping approaches has served us well, but we have to admit that it's a mess.
+
+## SMTPUTF8
+
+`SMTPUTF8` is another SMTP extension, defined in [RFC 6531](https://www.rfc-editor.org/rfc/rfc6531) in 2012. This essentially solves the whole problem, allowing the entire SMTP conversation — commands, headers, and message bodies — to be sent in raw, unencoded UTF-8.
+
+But there's a problem with this approach: adoption. If you send a UTF-8 message to a recipient whose mail server doesn't support this format, the sender has to somehow downgrade the message to make it survive a transition to 7-bit. This is a hard problem to solve, especially since there is no way to make a 7-bit system support UTF-8 in the local parts of addresses. This downgrade problem is what held up the adoption of `SMTPUTF8` in PHPMailer for many years, but in that time the *de facto* approach has become to simply fail in that situation, and tell the recipient it's time they upgraded their mail server 😅.
+
+The vast majority of large email providers (gmail, Yahoo, Microsoft, etc), mail servers (postfix, exim, IIS, etc), and mail clients (Apple Mail, Outlook, Thunderbird, etc) now all support SMTPUTF8, so the need for backward compatibility is no longer what it was.
+
+## SMTPUTF8 in PHPMailer
+
+Several other PHP email libraries have implemented a halfway solution to `SMTPUTF8`, adding only the ability to support UTF-8 in email addresses, not elsewhere in the protocol. I wanted PHPMailer to do it "the right way", and this has taken much longer. PHPMailer now supports UTF-8 everywhere, and does not need to use transfer or header encodings for UTF-8 text when connecting to an `SMTPUTF8`-capable mail server.
+
+This support is handled automatically: if you add an email address that requires UTF-8, PHPMailer will use UTF-8 for everything. If not, it will fall back to 7-bit and encode the message as necessary.
+
+The one place you will need to be careful is in the selection of the address validator. By default, PHPMailer uses PHP's built-in `filter_var` validator, which does not allow UTF-8 email addresses. When PHPMailer spots that you have submitted a UTF-8 address, but have not altered the default validator, it will automatically switch to using a UTF-8-compatible validator. As soon as you do this, any SMTP connection you make will *require* that the server you connect to supports `SMTPUTF8`. You can select this validator explicitly by setting `PHPMailer::$validator = 'eai'` (an acronym for Email Address Internationalization).
+
+### Postfix gotcha
+
+Postfix has supported `SMTPUTF8` for a long time, but it has a peculiarity that it does not always advertise that it does so. However, rather surprisingly, if you use UTF-8 in the conversation, it will work anyway.

+/**
+ * PHPMailer POP-Before-SMTP Authentication Class.
+ * Specifically for PHPMailer to use for RFC1939 POP-before-SMTP authentication.
+ * 1) This class does not support APOP authentication.
+ * 2) Opening and closing lots of POP3 connections can be quite slow. If you need
+ *   to send a batch of emails then just perform the authentication once at the start,
+ *   and then loop through your mail sending script. Providing this process doesn't
+ *   take longer than the verification period lasts on your POP3 server, you should be fine.
+ * 3) This is really ancient technology; you should only need to use it to talk to very old systems.
+ * 4) This POP3 class is deliberately lightweight and incomplete, implementing just
+ *   enough to do authentication.
+ *   If you want a more complete class there are other POP3 classes for PHP available.
