| PURPOSE: |
|
|
| Provide alternative IMAP library that doesn't rely on the standard |
|
|
| C-Client based version. This allows to function regardless |
|
|
| of whether or not the PHP build it's running on has IMAP |
|
|
| functionality built-in. |
|
|
| |
|
|
| Based on Iloha IMAP Library. See http://ilohamail.org/ for details |
