7 | * |
8 | * This plugin filters your inbox into different folders based upon given |
9 | * criteria. It is most useful for people who are subscibed to mailing lists |
10 | * to help organize their messages. The argument stands that filtering is |
11 | * not the place of the client, which is why this has been made a plugin for |
12 | * SquirrelMail. You may be better off using products such as Sieve or |
13 | * Procmail to do your filtering so it happens even when SquirrelMail isn't |
14 | * running. |
15 | * |
16 | * If you need help with this, or see improvements that can be made, please |
17 | * email me directly at the address above. I definately welcome suggestions |
18 | * and comments. This plugin, as is the case with all SquirrelMail plugins, |
19 | * is not directly supported by the developers. Please come to me off the |
20 | * mailing list if you have trouble with it. |
21 | * |
22 | * Also view plugins/README.plugins for more information. |
