John, Ok. There are exceptions to every rule. BW, I also strongly recommend against using the OS400 SMTP/POP. But I will modify my original statement to "It is almost never a good thing to modify your hosts file. Unless you are using OS400 brain dead SMTP". That better? <GD&R> (Translated: GDR=Grinning, Ducking & Running) Why don't I like the hosts file? Because you have to keep every machine in your network updated. And if you are sophisticated enough (or brave enough?) to run your own SMTP, HTTP, etc servers, DNS should not be a problem. DNS gives you a lot of flexibility. The hosts file gives you none.

Is it because if you change an IP address you have to go to every PC and change the host file? And according to IBM http://www-912.ibm.com/s_dir/SLKBase.nsf/3ff1161e61e6c7468625661300765a 3f/34879f5e413aa5cd8625697b0053f36a?OpenDocument some things have to be in the AS/400 host file. "Note: The Mail Router parameter must be an alphanumeric name and not an IP Address. Also, an entry must be made in the host table of the server to associate the name mailrelay to the IP Address 192.168.5.254." Mine is an IP address and works ok (V5R1), I did not see at what release that was at. "Note: If you wanted to receive mail for a second SMTP Domain named mail2.company.com, mail2.company.com would also be associated with the Interface 192.168.1.5." And this show it in the host file. I just mention these because someone said they put the name in the host file on the AS/400 (for an email problem) and it worked after that, and he was told that was a bad idea.
