Mark, <p>It sounds as if you need an extra routing step. Use the ADDTCPHTE command and use the IP address of the new server. You may see an immediate difference. <p>Dave

I already had that set to the new IP address and it still is giving me the bounce back error. The new mail server I set up requires authentication for outgoing messages because of relay reasons, how do I set that on my AS/400 settings?

For the purposes of the forum I will show how I fixed this. <p>It was not in my AS/400 setup at all. I had to go into my mail server setup. I naturally had all relaying turned off. I had to tell my mail server that it was ok to relay mail from ip address 192.168.5.88 (my as/400). That took care of it. <p>Thanks for your help, David.

I am trying to send mail from our AS/400. This worked for a couple of years until we changed mail servers. Our old mail server required a username of This e-mail address is being protected from spam bots, you need JavaScript enabled to view it . This was set up under Change Names for SMTP, jsmith was the SMTP User ID, and mydomain.com was the SMTP domain. <p>Now our new server requires a username of jsmith@mydomain (without the .com at the end). If I change the SMTP domain to mydomain, the email goes out, but they reply to is "jsmith@mydomain" and some servers wont accept that. <p>Also, I get a bounce back message reading the following: <p><!--mccodelink_begin--> <BR>
