or, I'm sure the "spammers" get "spammed" to some point as well..... so just
look in the message properties, get the server name, and go to work.

WSPingPro checks for open SMTP relays? I think that's going beyond
its charter, or at least the charter as I see it.

So, moving MS SMTP to a non-standard port in an Imail machine means
that MS SMTP better have an anti-relay setting.
Any port scanner will do that, returning all ports and the tcp/udp
services found on each one. NetScan Tools 4 has a very fine port
scanner, too. I don't remember how wide a network it will scan.
The best way for spammers to find open relays is simply to look them
up in ORBS or MAPS RSS databases.
