/**
 * Message and Spam Filter Plugin - Setup script
 *
 * This plugin filters your inbox into different folders based upon given
 * criteria.  It is most useful for people who are subscibed to mailing lists
 * 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.
 *
 * Also view plugins/README.plugins for more information.

 *     0.2) with
 * Since this line indicates the FIRST hop the email takes into my network,
 * I set my SpamFilters_YourHop to 'by firewall.persistence.com' but any
 * case-sensitive string will do.  You can set it to something found on
 * every line in the header (like ' ') if you want to scan all IPs in
 * the header (lots of false alarms here tho).
