0a1dc88e 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
14 * email me directly at the address above. I definately welcome suggestions
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.
