I have a fresh install of RHEL4. Zimbra installed flawlessly with no errors in the logs. I can successfully send email to accounts that I setup in Zimbra but not to external addresses. Here's what Outlook Express errors with:
Server Response: '554
: Relay access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79
I've looked at all teh relevant posts in these formus but nothing seems to work. Here's my host file:
127.0.0.1 localhost.localdomain localhost
126.96.36.199 ai.4ph.com ai srv161.carpathiahost.net srv161
I've also tried (everything on 1 live w/ 127.0.0.1):
127.0.0.1 localhost.localdomain localhost ai.4ph.com ai srv161.carpathiahost.net srv161
in the Zimbra admin/MTA I have:
webmail MTA: localhost (also tried ai.4ph.com)
dns lookups: checked:
everything else unchecked
I have tried what mathematically might be every possible checkbox combination without success.
Any help would be greatly appreciated.
