Haven't tried some non-standard port, just default. Looks like it is all port 25 traffic. I will check with my upstream but I seriously doubt that one.
Doesn't appear to be hardware specific as all are 411AH or 433AH that the traffic passes through. I do have a firewall in place on every router but there are no rules in it for port 25.
