| 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() |
|---|
| 26 | VERSION: |
|---|
| 27 | IlohaMail-0.9-20050415 |
|---|
| 28 | CHANGES: |
|---|
| 29 | File altered by Thomas Bruederli <roundcube@gmail.com> |
|---|
| 30 | to fit enhanced equirements by the RoundCube Webmail: |
|---|
| 31 | - Added list of server capabilites and check these before invoking commands |
|---|
| 32 | - Added junk flag to iilBasicHeader |
|---|
| 33 | - Enhanced error reporting on fsockopen() |
|---|
| 34 | - Additional parameter for SORT command |
|---|
| 35 | - Removed Call-time pass-by-reference because deprecated |
|---|
| 36 | - Parse charset from content-type in iil_C_FetchHeaders() |
|---|
| 37 | - Enhanced heaer sorting |
|---|
| 38 | - Pass message as reference in iil_C_Append (to save memory) |
|---|
| 39 | - Added BCC and REFERENCE to the list of headers to fetch in iil_C_FetchHeaders() |
|---|
| 40 | - Leave messageID unchanged in iil_C_FetchHeaders() |
|---|
| 41 | - Avoid stripslahes in iil_Connect() |
|---|
| 42 | - Escape quotes and backslashes in iil_C_Login() |
|---|
| 43 | - Added patch to iil_SortHeaders() by Richard Green |
|---|
| 44 | - Removed <br> from error messages (better for logging) |
|---|
| 45 | - Added patch to iil_C_Sort() enabling UID SORT commands |
|---|
| 46 | - Added function iil_C_ID2UID() |
|---|
| 47 | - Casting date parts in iil_StrToTime() to avoid mktime() warnings |
|---|
| 48 | - Also acceppt LIST responses in iil_C_ListSubscribed() |
|---|
| 49 | - Sanity check of $message_set in iil_C_FetchHeaders(), iil_C_FetchHeaderIndex(), iil_C_FetchThreadHeaders() |
|---|
| 50 | - Implemented UID FETCH in iil_C_FetchHeaders() |
|---|
| 51 | - Abort do-loop on socket errors (fgets returns false) |
|---|
| 52 | - Removed some debuggers (echo ...) |
