+ *    pfSense spamd mousetrap
+ *    (C)2006 Scott Ullrich
+ *
+ *    Reads in an external list of c/r
+ *    seperated valid e-mail addresses
+ *    and then looks to see waiting grey-
+ *    listed servers.   if the server is
+ *    sending to an invalid e-mail address
+ *    then add them to spamtrap.
+ *
+ *    Directions for usage:
+ *       1.  Download this script to the /root/ directory on your pfSense installation.
+ *       2.  chmod a+rx spamd_verify_to_address.php
+ *       3.  Edit $server_to_pull_data_from to point to a location containing a list of
+ *           all valid email addresses c/r seperated.
+ *       4.  Add spamd_verify_to_address.php to cron or run it by invoking 
+ *          ./spamd_verify_to_address.php manually.
+ *
+ *    XXX/TODO:
+ *        * Add flag to blacklist a server after receiving X
+ *          attempts at a delivery with invalid to: addresses.
+ *
