- * This plugin filters your inbox into different folders based upon given

- * to help organize their messages. The argument stands that filtering is
- * not the place of the client, which is why this has been made a plugin for
- * SquirrelMail. You may be better off using products such as Sieve or
- * Procmail to do your filtering so it happens even when SquirrelMail isn't
- * running.
- *
- * If you need help with this, or see improvements that can be made, please
- * email me directly at the address above. I definately welcome suggestions
- * and comments. This plugin, as is the case with all SquirrelMail plugins,
- * is not directly supported by the developers. Please come to me off the
- * mailing list if you have trouble with it.
