As part of our ongoing quality efforts, we have upgraded Mail Pathfinder, and are modifying the IP addresses of the pool of servers that will be delivering mail to your primary mail server. For optimal spam protection, we recommend firewalling off your mail server and ports to only accept connections from our Mail Pathfinder pool. If you already have firewall rules in place, you will need to update them to reflect the pool IPs below by Tuesday Aug 21, 2012. (We have listed your mail server IP/Port below for your convenience.) Please ensure the Mail Pathfinder pool addresses below are able to access your mail server before Aug 21, 2012.
