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
|
|

|
|
- Implemented UID FETCH in iil_C_FetchHeaders()
|
|
- Abort do-loop on socket errors (fgets returns false)
|
|
- $ICL_SSL is not boolean anymore but contains the connection schema (ssl or tls)
