TO DO
=====
* Add code to allow Z-Push to follow LDAP referrals, for use in master-slave configurations.
* Switch to using mail() rather than imap_mail() to send email.
* Check existance of private_address_book before allowing LDAP contacts to be added.
* Better "from" and "return-path" headers (maybe look up full name from server?).
* Investigate dummy and filestorage backend errors.
* Get CalDav backend to sync multiple calenders, maybe using categories, or implement iPhone-like multiple calendar folders 
* Implement iRemoteWipe remote wipe system. For more info see:

* Implement a mechanism for clearing the BadMessage list on a regular basis

1.3_fabit-4
===========
* Small bug in IMAP backend that only seems to happen when there are more than 100 emails to be synced. (Not true).
   - Fixed by adding a "BadMessage" list, done by creating files with the message id number. You need to create a
     BadMessage directory that the Apache user has write permissions to (like "state"). Under there an IMAP folder will
     be automatically created, and user there one for each user. If imap_body() crashes, or there is something in 
     imap_errors(), the message will be marked as bad. This directory should probably be cleared out on a regular basis.
* Implemented CalDAV tasks.
* Works with PHP 5.3 without errors.
* Got rid of unused backends.

1.3_fabit-3
===========
* Assorted bug fixes, mainly for caldav.

1.3_fabit-2
===========
* Got rid of "Non-static method Mail_RFC822::parseAddressList() should not be called statically, 
  assuming $this from incompatible context (2048)" error from RFC" in imap.php.
* Added BCC headers to copy of sent mail.
* CalDAV backend (Events only) (Decided not to implement old style file based iCal)

1.3_fabit-1
===========
* Uses Bas' combined backend.
* Sync's Contacts via LDAP (designed to work with Contagged) - Original code copyright Rutger Terborg.
* Fixed "message contains bare newlines" bug when saving Sent Mail to Cyrus IMAP server.
