	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()

f7bfec	50	- Implemented UID FETCH in iil_C_FetchHeaders()
9e0bb6	51	- Abort do-loop on socket errors (fgets returns false)
5bc0ab	52	- $ICL_SSL is not boolean anymore but contains the connection schema (ssl or tls)
0284c2	53	- Removed some debuggers (echo ...)
ca4c08	54	File altered by Aleksander Machniak <alec@alec.pl>
