How to Rebuild Postfix Mail Server

in the cwp menu you have postfix manager where you can rebuild the mail server

Thanks, but running Posfix is what I believed started the problem. The server has only been running for a couple of weeks, and I didn't have a problem right after installing the panel until I ran Posfix. I was hoping a set of commands would just let me remove and re-install the mail services to fix my problem.

Try to keep amavis, clam and spamassasin running but let postfix bypass them all..
in mail.cf comment this line "content_filter = smtp-amavis:[127.0.0.1]:10024"
in master.cf comment this line "-o content_filter=smtp-amavis:127.0.0.1:10024"
restart postfix, will make it ignore both amavis, clam and spamassasin

then one by one enable them

do you want to say main.cf ??

You have a troubles with yum. Fix it before install!

Seems you have a problem in yum or RPM database.
