-/********************************************************
-
- FILE: include/imap.inc
- PURPOSE:
- Provide alternative IMAP library that doesn't rely on the standard
- C-Client based version. This allows IlohaMail to function regardless
- of whether or not the PHP build it's running on has IMAP functionality
- built-in.
- USEAGE:
- Function containing "_C_" in name require connection handler to be
- passed as one of the parameters. To obtain connection handler, use
- iil_Connect()
- VERSION:
- IlohaMail-0.9-20050415
- CHANGES:
- File altered by Thomas Bruederli <roundcube@gmail.com>
- to fit enhanced equirements by the RoundCube Webmail:
- - Added list of server capabilites and check these before invoking commands
- - Added junk flag to iilBasicHeader
- - Enhanced error reporting on fsockopen()
- - Additional parameter for SORT command
- - Removed Call-time pass-by-reference because deprecated
- - Parse charset from content-type in iil_C_FetchHeaders()
- - Enhanced heaer sorting
- - Pass message as reference in iil_C_Append (to save memory)
- - Added BCC and REFERENCE to the list of headers to fetch in iil_C_FetchHeaders()
- - Leave messageID unchanged in iil_C_FetchHeaders()
- - Avoid stripslahes in iil_Connect()
- - Escape quotes and backslashes in iil_C_Login()
- - Added patch to iil_SortHeaders() by Richard Green
- - Removed <br> from error messages (better for logging)
- - Added patch to iil_C_Sort() enabling UID SORT commands
- - Added function iil_C_ID2UID()
- - Casting date parts in iil_StrToTime() to avoid mktime() warnings
- - Also acceppt LIST responses in iil_C_ListSubscribed()
- - Sanity check of $message_set in iil_C_FetchHeaders(), iil_C_FetchHeaderIndex(), iil_C_FetchThreadHeaders()
- - Implemented UID FETCH in iil_C_FetchHeaders()
- - Abort do-loop on socket errors (fgets returns false)
- - $ICL_SSL is not boolean anymore but contains the connection schema (ssl or tls)
- - Removed some debuggers (echo ...)
- File altered by Aleksander Machniak <alec@alec.pl>
- - trim(chop()) replaced by trim()
- - added iil_Escape()/iil_UnEscape() with support for " and \ in folder names
- - support \ character in username in iil_C_Login()
- - fixed iil_MultLine(): use iil_ReadBytes() instead of iil_ReadLine()
- - fixed iil_C_FetchStructureString() to handle many literal strings in response
- - removed hardcoded data size in iil_ReadLine()
- - added iil_PutLine() wrapper for fputs()
- - code cleanup and identation fixes
- - removed flush() calls in iil_C_HandlePartBody() to prevent from memory leak (#1485187)
- - don't return "??" from iil_C_GetQuota()
- - RFC3501 [7.1] don't call CAPABILITY if was returned in server
- optional resposne in iil_Connect(), added iil_C_GetCapability()
- - remove 'undisclosed-recipients' string from 'To' header
- - iil_C_HandlePartBody(): added 6th argument and fixed endless loop
- - added iil_PutLineC()
- - fixed iil_C_Sort() to support very long and/or divided responses
- - added BYE/BAD response simple support for endless loop prevention
- - added 3rd argument in iil_StartsWith* functions
- - fix iil_C_FetchPartHeader() in some cases by use of iil_C_HandlePartBody()
- - allow iil_C_HandlePartBody() to fetch whole message
- - optimize iil_C_FetchHeaders() to use only one FETCH command
- - added 4th argument to iil_Connect()
- - allow setting rootdir and delimiter before connect
- - support multiquota result
- - include BODYSTRUCTURE in iil_C_FetchHeaders()
- - added iil_C_FetchMIMEHeaders() function
- - added \* flag support
- - use PREG instead of EREG
- - removed caching functions
- - handling connection startup response
- - added UID EXPUNGE support
- - fixed problem with double quotes and spaces in folder names in LIST and LSUB
- - rewritten iil_C_FetchHeaderIndex()
