	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()
