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
