	16	FILE: include/imap.inc
	17	PURPOSE:
	18	Provide alternative IMAP library that doesn't rely on the standard
	19	C-Client based version. This allows IlohaMail to function regardless
	20	of whether or not the PHP build it's running on has IMAP functionality
	21	built-in.
	22	USEAGE:
	23	Function containing "_C_" in name require connection handler to be
	24	passed as one of the parameters. To obtain connection handler, use
	25	iil_Connect()
0284c2	26	VERSION:
T	27	IlohaMail-0.9-20050415
	28	CHANGES:
	29	File altered by Thomas Bruederli <roundcube@gmail.com>
	30	to fit enhanced equirements by the RoundCube Webmail:
	31	- Added list of server capabilites and check these before invoking commands
	32	- Added junk flag to iilBasicHeader
	33	- Enhanced error reporting on fsockopen()
	34	- Additional parameter for SORT command
	35	- Removed Call-time pass-by-reference because deprecated
	36	- Parse charset from content-type in iil_C_FetchHeaders()
	37	- Enhanced heaer sorting
	38	- Pass message as reference in iil_C_Append (to save memory)
f88d41	39	- Added BCC and REFERENCE to the list of headers to fetch in iil_C_FetchHeaders()
T	40	- Leave messageID unchanged in iil_C_FetchHeaders()
	41	- Avoid stripslahes in iil_Connect()
0d361b	42	- Added patch to iil_SortHeaders() by Richard Green
8c2e58	43	- Removed <br> from error messages (better for logging)
e6f360	44	- Added patch to iil_C_Sort() enabling UID SORT commands
T	45	- Added function iil_C_ID2UID()
6eeb17	46	- Casting date parts in iil_StrToTime() to avoid mktime() warnings
0284c2	47	- Removed some debuggers (echo ...)
