|
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()
|
|
- 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
|
|
- Removed some debuggers (echo ...)
