| 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. |
