3 | * Message and Spam Filter Plugin - Filtering Functions |
15e6162e |
4 | * |
15e6162e |
5 | * This plugin filters your inbox into different folders based upon given |
6 | * criteria. It is most useful for people who are subscibed to mailing lists |
7 | * to help organize their messages. The argument stands that filtering is |
8 | * not the place of the client, which is why this has been made a plugin for |
9 | * SquirrelMail. You may be better off using products such as Sieve or |
10 | * Procmail to do your filtering so it happens even when SquirrelMail isn't |
11 | * running. |
12 | * |
13 | * If you need help with this, or see improvements that can be made, please |
9c655416 |
14 | * email me directly at the address above. I definitely welcome suggestions |
15e6162e |
15 | * and comments. This plugin, as is the case with all SquirrelMail plugins, |
16 | * is not directly supported by the developers. Please come to me off the |
17 | * mailing list if you have trouble with it. |
18 | * |
19 | * Also view plugins/README.plugins for more information. |
