| 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() |
