Welcome to the forums.

This subject has been covered many, many times in the forums. Check to see if the mynetworks is set correctly. Is the use DNS option set in the Admin UI? Do you have a correct /etc/hosts file and DNS A & MX records pointing at your zimbra server, check with the following commands run on the zimbra server:

Code:

host `hostname` <-- type as-is with backticks not single quotes dig yourdomain.com any dig yourdomain.com mx

and post the results.

Please post the details of the commands I gave you earlier. Which operating system is this? What errors do you have in the logs? Which version/release of zimbra?

RHEL 5
Zimbra 4.5.10
When use POP3 (SSL)
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was XXX@yahoo.com'. Subject 'goi', Account: XXXX.XXXX.XXXX.XXXX, Server: XXXX.XXXX.XXXX.XXXX', Protocol: SMTP, Server Response: '554 <XXX@yahoo.com'>: Relay access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79

First of all, I meant the output from these commands:

Code:

host `hostname` <-- type as-is with backticks not single quotes dig yourdomain.com any dig yourdomain.com mx

Secondly, you need to have your LAN subnet in the mynetworks field so it should read '127.0.0.0/8 192.168..10/24' or whatever your LAN is.
