I just attempted to install a clean version on RHES 4. I used the basic setup on RH and attempted to install Zimbra Beta 2. Durring the install, I got a port conflict on port 25. By what, I am not sure. It is a clean RH install. Once the install completed, I can not start the MTA service. When I view the logs, I see the following:
Nov 23 09:45:41 mail postfix/postfix-script: warning: not owned by root: /opt/zimbra/postfix-2.2.3/conf/main.cf
Nov 23 09:45:41 mail postfix/postfix-script: starting the Postfix mail system
Nov 23 09:45:41 mail postfix/master: fatal: bind 0.0.0.0 port 25: Address already in use
Can anyone help guide me in the right direction? Thanks in advance!
