#PHPMailer Extras

These classes provide optional additional functions to PHPMailer. 

These are not loaded by the PHPMailer autoloader, so in some cases you may need to `require` them yourself before using them. 

##HTML2Text

This class was written by Jon Abernathy and provides a simple conversion of HTML to plain-text, while attempting to preserve some aspects of the formatting.  It is used in PHPMailer if you set the `advanced` parameter to `true` in either the `msgHTML()` or `html2text` methods of PHPMailer. 

##EasyPeasyICS

This class was originally written by Manuel Reinhard and provides a simple means of generating ICS/vCal files that are used in sending calendar events.  PHPMailer does not use it directly, but you can use it to generate content appropriate for placing in the `Ical` property of PHPMailer.  The PHPMailer project is now its official home as Manuel has given permission for that and is no longer maintaining it himself. 

##htmlfilter

This class by Konstantin Riabitsev and Jim Jagielski implements HTML filtering to remove potentially malicious tags, such as `<script>` or `onclick=` attributes that can result in XSS attacks.  This is a simple filter and is not as comprehensive as [HTMLawed](http://www.bioinformatics.org/phplabware/internal_utilities/htmLawed/) or [HTMLPurifier](http://htmlpurifier.org), but it's easier to use and considerably better than nothing!  PHPMailer does not use it directly, but you may want to apply it to user-supplied HTML before using it as a message body. 

##NTLM_SASL_client

This class by Manuel Lemos (bundled with permission) adds the ability to authenticate with Microsoft Windows mail servers that use NTLM-based authentication.  It is used by PHPMailer if you send via SMTP and set the `AuthType` property to `NTLM`; you will also need to use the `Realm` and `Workstation` properties.
