| 13 | PURPOSE: | | |
| 14 | Provide alternative IMAP library that doesn't rely on the standard | | |
| 15 | C-Client based version. This allows to function regardless | | |
| 16 | of whether or not the PHP build it's running on has IMAP | | |
| 17 | functionality built-in. | | |
| 18 | | | |
| 19 | Based on Iloha IMAP Library. See http://ilohamail.org/ for details | | |
