-ChangeLog
-
-NOTE: THIS VERSION OF PHPMAILER IS DESIGNED FOR PHP5/PHP6.
-      IT WILL NOT WORK WITH PHP4.
-
-Version 5.0.2 (May 24, 2009)
-* Fix for missing attachments when inline graphics are present
-* Fix for missing Cc in header when using SMTP (mail was sent,
-  but not displayed in header -- Cc receiver only saw email To: 
-  line and no Cc line, but did get the email (To receiver
-  saw same)
-
-Version 5.0.1 (April 05, 2009)
-* Temporary fix for missing attachments
-
-Version 5.0.0 (April 02, 2009)
-
-* With the release of this version, we are initiating a new version numbering
-  system to differentiate from the PHP4 version of PHPMailer.
-* Most notable in this release is fully object oriented code.
-class.smtp.php:
-* Refactored class.smtp.php to support new exception handling
-  code size reduced from 29.2 Kb to 25.6 Kb
-* Removed unnecessary functions from class.smtp.php:
-  public function Expand($name) {
-  public function Help($keyword="") {
-  public function Noop() {
-  public function Send($from) {
-  public function SendOrMail($from) {
-  public function Verify($name) {
-class.phpmailer.php:
-* Refactored class.phpmailer.php with new exception handling
-* Changed processing functionality of Sendmail and Qmail so they cannot be
-  inadvertently used
-* removed getFile() function, just became a simple wrapper for
-  file_get_contents()
-* added check for PHP version (will gracefully exit if not at least PHP 5.0)
-class.phpmailer.php enhancements
-* enhanced code to check if an attachment source is the same as an embedded or
-  inline graphic source to eliminate duplicate attachments
-New /test_script
-* We have written a test script you can use to test the script as part of your
-  installation. Once you press submit, the test script will send a multi-mime
-  email with either the message you type in or an HTML email with an inline
-  graphic. Two attachments are included in the email (one of the attachments
-  is also the inline graphic so you can see that only one copy of the graphic
-  is sent in the email). The test script will also display the functional
-  script that you can copy/paste to your editor to duplicate the functionality.
-New examples
-* All new examples in both basic and advanced modes. Advanced examples show
-  Exception handling.
-PHPDocumentator (phpdocs) documentation for PHPMailer version 5.0.0
-* all new documentation
-
-Please note: the website has been updated to reflect the changes in PHPMailer
-version 5.0.0. http://phpmailer.codeworxtech.com/
-
-Version 2.3 (November 06, 2008)
-
-* added Arabic language (many thanks to Bahjat Al Mostafa)
-* removed English language from language files and made it a default within
-  class.phpmailer.php - if no language is found, it will default to use
-  the english language translation
-* fixed public/private declarations
-* corrected line 1728, $basedir to $directory
-* added $sign_cert_file to avoid improper duplicate use of $sign_key_file
-* corrected $this->Hello on line 612 to $this->Helo
-* changed default of $LE to "\r\n" to comply with RFC 2822. Can be set by the user
-  if default is not acceptable
-* removed trim() from return results in EncodeQP
-* /test and three files it contained are removed from version 2.3
-* fixed phpunit.php for compliance with PHP5
-* changed $this->AltBody = $textMsg; to $this->AltBody = html_entity_decode($textMsg);
-* We have removed the /phpdoc from the downloads. All documentation is now on
-  the http://phpmailer.codeworxtech.com website.
-
-Version 2.2.1 () July 19 2008
-
-* fixed line 1092 in class.smtp.php (my apologies, error on my part)
-
-Version 2.2 () July 15 2008
-
-* Fixed redirect issue (display of UTF-8 in thank you redirect)
-* fixed error in getResponse function declaration (class.pop3.php)
-* PHPMailer now PHP6 compliant
-* fixed line 1092 in class.smtp.php (endless loop from missing = sign)
-
-Version 2.1 (Wed, June 04 2008)
-
-** NOTE: WE HAVE A NEW LANGUAGE VARIABLE FOR DIGITALLY SIGNED S/MIME EMAILS.
-   IF YOU CAN HELP WITH LANGUAGES OTHER THAN ENGLISH AND SPANISH, IT WOULD BE
-   APPRECIATED.
-
-* added S/MIME functionality (ability to digitally sign emails)
-  BIG THANKS TO "sergiocambra" for posting this patch back in November 2007.
-  The "Signed Emails" functionality adds the Sign method to pass the private key
-  filename and the password to read it, and then email will be sent with
-  content-type multipart/signed and with the digital signature attached.
-* fully compatible with E_STRICT error level
-  - Please note:
-    In about half the test environments this development version was subjected
-    to, an error was thrown for the date() functions used (line 1565 and 1569).
-    This is NOT a PHPMailer error, it is the result of an incorrectly configured
-    PHP5 installation. The fix is to modify your 'php.ini' file and include the
-    date.timezone = America/New York
-    directive, to your own server timezone
-  - If you do get this error, and are unable to access your php.ini file:
-    In your PHP script, add
-    date_default_timezone_set('America/Toronto');
-    - do not try to use
-    $myVar = date_default_timezone_get();
-    as a test, it will throw an error.
-* added ability to define path (mainly for embedded images)
-  function MsgHTML($message,$basedir='') ... where:
-  $basedir is the fully qualified path
-* fixed MsgHTML() function:
-  - Embedded Images where images are specified by <protocol>:// will not be altered or embedded
-* fixed the return value of SMTP exit code ( pclose )
-* addressed issue of multibyte characters in subject line and truncating
-* added ability to have user specified Message ID
-  (default is still that PHPMailer create a unique Message ID)
-* corrected unidentified message type to 'application/octet-stream'
-* fixed chunk_split() multibyte issue (thanks to Colin Brown, et al).
-* added check for added attachments
-* enhanced conversion of HTML to text in MsgHTML (thanks to "brunny")
-
-Version 2.1.0beta2 (Sun, Dec 02 2007)
-* implemented updated EncodeQP (thanks to coolbru, aka Marcus Bointon)
-* finished all testing, all known bugs corrected, enhancements tested
-- note: will NOT work with PHP4.
-
-please note, this is BETA software
-** DO NOT USE THIS IN PRODUCTION OR LIVE PROJECTS
-INTENDED STRICTLY FOR TESTING
-
-Version 2.1.0beta1
-please note, this is BETA software
-** DO NOT USE THIS IN PRODUCTION OR LIVE PROJECTS
-INTENDED STRICTLY FOR TESTING
-
-Version 2.0.0 rc2 (Fri, Nov 16 2007), interim release
-* implements new property to control VERP in class.smtp.php
-  example (requires instantiating class.smtp.php):
-  $mail->do_verp = true;
-* POP-before-SMTP functionality included, thanks to Richard Davey
-  (see class.pop3.php & pop3_before_smtp_test.php for examples)
-* included example showing how to use PHPMailer with GMAIL
-* fixed the missing Cc in SendMail() and Mail()
-
-******************
-A note on sending bulk emails:
-
-If the email you are sending is not personalized, consider using the
-"undisclosed-recipient:;" strategy. That is, put all of your recipients
-in the Bcc field and set the To field to "undisclosed-recipients:;".
-It's a lot faster (only one send) and saves quite a bit on resources.
-Contrary to some opinions, this will not get you listed in spam engines -
-it's a legitimate way for you to send emails.
-
-A partial example for use with PHPMailer:
-
-$mail->AddAddress("undisclosed-recipients:;");
-$mail->AddBCC("email1@anydomain.com,email2@anyotherdomain.com,email3@anyalternatedomain.com");
-
-Many email service providers restrict the number of emails that can be sent
-in any given time period. Often that is between 50 - 60 emails maximum
-per hour or per send session.
-
-If that's the case, then break up your Bcc lists into chunks that are one
-less than your limit, and put a pause in your script.
-*******************
-
-Version 2.0.0 rc1 (Thu, Nov 08 2007), interim release
-* dramatically simplified using inline graphics ... it's fully automated and requires no user input

-* removed the need to set the IsHTML property (set automatically)
-* added Estonian language file by Indrek P&auml;ri

-  $mail->set('X-Priority', '3');
-  $mail->set('X-MSMail-Priority', 'Normal');
-* fixed warning message in SMTP get_lines method
-* added TLS/SSL SMTP support
-  example of use:

+ChangeLog
+
+NOTE: THIS VERSION OF PHPMAILER IS DESIGNED FOR PHP5/PHP6.
+      IT WILL NOT WORK WITH PHP4.
+
+Version 5.1 (October 20, 2009)
+* fixed filename issue with AddStringAttachment (thanks to Tony)
+* fixed "SingleTo" property, now works with Senmail, Qmail, and SMTP in
+  addition to PHP mail()
+* added DKIM digital signing functionality
+  New properties:
+  - DKIM_domain (sets the domain name)
+  - DKIM_private (holds DKIM private key)
+  - DKIM_passphrase (holds your DKIM passphrase)
+  - DKIM_selector (holds the DKIM "selector")
+  - DKIM_identity (holds the identifying email address)
+* added callback function support
+  - callback function parameters include:
+    result, to, cc, bcc, subject and body
+  * see the test/test_callback.php file for usage.
+* added "auto" identity functionality
+  - can automatically add:
+    - Return-path (if Sender not set)
+    - Reply-To (if ReplyTo not set)
+  - can be disabled:
+    - $mail->SetFrom('yourname@yourdomain.com','First Last',false);
+    - or by adding the $mail->Sender and/or $mail->ReplyTo properties
+  Note: "auto" identity added to help with emails ending up in spam
+  or junk boxes because of missing headers
+
+Version 5.0.2 (May 24, 2009)
+* Fix for missing attachments when inline graphics are present
+* Fix for missing Cc in header when using SMTP (mail was sent,
+  but not displayed in header -- Cc receiver only saw email To: 
+  line and no Cc line, but did get the email (To receiver
+  saw same)
+
+Version 5.0.1 (April 05, 2009)
+* Temporary fix for missing attachments
+
+Version 5.0.0 (April 02, 2009)
+
+* With the release of this version, we are initiating a new version numbering
+  system to differentiate from the PHP4 version of PHPMailer.
+* Most notable in this release is fully object oriented code.
+class.smtp.php:
+* Refactored class.smtp.php to support new exception handling
+  code size reduced from 29.2 Kb to 25.6 Kb
+* Removed unnecessary functions from class.smtp.php:
+  public function Expand($name) {
+  public function Help($keyword="") {
+  public function Noop() {
+  public function Send($from) {
+  public function SendOrMail($from) {
+  public function Verify($name) {
+class.phpmailer.php:
+* Refactored class.phpmailer.php with new exception handling
+* Changed processing functionality of Sendmail and Qmail so they cannot be
+  inadvertently used
+* removed getFile() function, just became a simple wrapper for
+  file_get_contents()
+* added check for PHP version (will gracefully exit if not at least PHP 5.0)
+class.phpmailer.php enhancements
+* enhanced code to check if an attachment source is the same as an embedded or
+  inline graphic source to eliminate duplicate attachments
+New /test_script
+* We have written a test script you can use to test the script as part of your
+  installation. Once you press submit, the test script will send a multi-mime
+  email with either the message you type in or an HTML email with an inline
+  graphic. Two attachments are included in the email (one of the attachments
+  is also the inline graphic so you can see that only one copy of the graphic
+  is sent in the email). The test script will also display the functional
+  script that you can copy/paste to your editor to duplicate the functionality.
+New examples
+* All new examples in both basic and advanced modes. Advanced examples show
+  Exception handling.
+PHPDocumentator (phpdocs) documentation for PHPMailer version 5.0.0
+* all new documentation
+
+Please note: the website has been updated to reflect the changes in PHPMailer
+version 5.0.0. http://phpmailer.codeworxtech.com/
+
+Version 2.3 (November 06, 2008)
+
+* added Arabic language (many thanks to Bahjat Al Mostafa)
+* removed English language from language files and made it a default within
+  class.phpmailer.php - if no language is found, it will default to use
+  the english language translation
+* fixed public/private declarations
+* corrected line 1728, $basedir to $directory
+* added $sign_cert_file to avoid improper duplicate use of $sign_key_file
+* corrected $this->Hello on line 612 to $this->Helo
+* changed default of $LE to "\r\n" to comply with RFC 2822. Can be set by the user
+  if default is not acceptable
+* removed trim() from return results in EncodeQP
+* /test and three files it contained are removed from version 2.3
+* fixed phpunit.php for compliance with PHP5
+* changed $this->AltBody = $textMsg; to $this->AltBody = html_entity_decode($textMsg);
+* We have removed the /phpdoc from the downloads. All documentation is now on
+  the http://phpmailer.codeworxtech.com website.
+
+Version 2.2.1 () July 19 2008
+
+* fixed line 1092 in class.smtp.php (my apologies, error on my part)
+
+Version 2.2 () July 15 2008
+
+* Fixed redirect issue (display of UTF-8 in thank you redirect)
+* fixed error in getResponse function declaration (class.pop3.php)
+* PHPMailer now PHP6 compliant
+* fixed line 1092 in class.smtp.php (endless loop from missing = sign)
+
+Version 2.1 (Wed, June 04 2008)
+
+** NOTE: WE HAVE A NEW LANGUAGE VARIABLE FOR DIGITALLY SIGNED S/MIME EMAILS.
+   IF YOU CAN HELP WITH LANGUAGES OTHER THAN ENGLISH AND SPANISH, IT WOULD BE
+   APPRECIATED.
+
+* added S/MIME functionality (ability to digitally sign emails)
+  BIG THANKS TO "sergiocambra" for posting this patch back in November 2007.
+  The "Signed Emails" functionality adds the Sign method to pass the private key
+  filename and the password to read it, and then email will be sent with
+  content-type multipart/signed and with the digital signature attached.
+* fully compatible with E_STRICT error level
+  - Please note:
+    In about half the test environments this development version was subjected
+    to, an error was thrown for the date() functions used (line 1565 and 1569).
+    This is NOT a PHPMailer error, it is the result of an incorrectly configured
+    PHP5 installation. The fix is to modify your 'php.ini' file and include the
+    date.timezone = America/New York
+    directive, to your own server timezone
+  - If you do get this error, and are unable to access your php.ini file:
+    In your PHP script, add
+    date_default_timezone_set('America/Toronto');
+    - do not try to use
+    $myVar = date_default_timezone_get();
+    as a test, it will throw an error.
+* added ability to define path (mainly for embedded images)
+  function MsgHTML($message,$basedir='') ... where:
+  $basedir is the fully qualified path
+* fixed MsgHTML() function:
+  - Embedded Images where images are specified by <protocol>:// will not be altered or embedded
+* fixed the return value of SMTP exit code ( pclose )
+* addressed issue of multibyte characters in subject line and truncating
+* added ability to have user specified Message ID
+  (default is still that PHPMailer create a unique Message ID)
+* corrected unidentified message type to 'application/octet-stream'
+* fixed chunk_split() multibyte issue (thanks to Colin Brown, et al).
+* added check for added attachments
+* enhanced conversion of HTML to text in MsgHTML (thanks to "brunny")
+
+Version 2.1.0beta2 (Sun, Dec 02 2007)
+* implemented updated EncodeQP (thanks to coolbru, aka Marcus Bointon)
+* finished all testing, all known bugs corrected, enhancements tested
+- note: will NOT work with PHP4.
+
+please note, this is BETA software
+** DO NOT USE THIS IN PRODUCTION OR LIVE PROJECTS
+INTENDED STRICTLY FOR TESTING
+
+Version 2.1.0beta1
+please note, this is BETA software
+** DO NOT USE THIS IN PRODUCTION OR LIVE PROJECTS
+INTENDED STRICTLY FOR TESTING
+
+Version 2.0.0 rc2 (Fri, Nov 16 2007), interim release
+* implements new property to control VERP in class.smtp.php
+  example (requires instantiating class.smtp.php):
+  $mail->do_verp = true;
+* POP-before-SMTP functionality included, thanks to Richard Davey
+  (see class.pop3.php & pop3_before_smtp_test.php for examples)
+* included example showing how to use PHPMailer with GMAIL
+* fixed the missing Cc in SendMail() and Mail()
+
+******************
+A note on sending bulk emails:
+
+If the email you are sending is not personalized, consider using the
+"undisclosed-recipient:;" strategy. That is, put all of your recipients
+in the Bcc field and set the To field to "undisclosed-recipients:;".
+It's a lot faster (only one send) and saves quite a bit on resources.
+Contrary to some opinions, this will not get you listed in spam engines -
+it's a legitimate way for you to send emails.
+
+A partial example for use with PHPMailer:
+
+$mail->AddAddress("undisclosed-recipients:;");
+$mail->AddBCC("email1@anydomain.com,email2@anyotherdomain.com,email3@anyalternatedomain.com");
+
+Many email service providers restrict the number of emails that can be sent
+in any given time period. Often that is between 50 - 60 emails maximum
+per hour or per send session.
+
+If that's the case, then break up your Bcc lists into chunks that are one
+less than your limit, and put a pause in your script.
+*******************
+
+Version 2.0.0 rc1 (Thu, Nov 08 2007), interim release
+* dramatically simplified using inline graphics ... it's fully automated and requires no user input
+* added automatic document type detection for attachments and pictures
+* added MsgHTML() function to replace Body tag for HTML emails
+* fixed the SendMail security issues (input validation vulnerability)
+* enhanced the AddAddresses functionality so that the "Name" portion is used in the email address
+* removed the need to use the AltBody method (set from the HTML, or default text used)
+* set the PHP Mail() function as the default (still support SendMail, SMTP Mail)
+* removed the need to set the IsHTML property (set automatically)
+* added Estonian language file by Indrek P&auml;ri
+* added header injection patch
+* added "set" method to permit users to create their own pseudo-properties like 'X-Headers', etc.
+  example of use:
+  $mail->set('X-Priority', '3');
+  $mail->set('X-MSMail-Priority', 'Normal');
+* fixed warning message in SMTP get_lines method
+* added TLS/SSL SMTP support
+  example of use:
+  $mail = new PHPMailer();
+  $mail->Mailer = "smtp";
+  $mail->Host = "smtp.example.com";
+  $mail->SMTPSecure   = "tls"; // option
+  //$mail->SMTPSecure   = "ssl";  // option
+  ...
+  $mail->Send();
