+ 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()
