Extremely-- and I know that Zimbra is flat out not supported under 
CentOS, by their own decision.  If this is community edition, it's a 
different kettle of fish entirely.

I tried posting on the Zimbra forums after reading the docs, but my post was labeled as SPAM and the moderators have not replied to my private message to get my post reviewed. Who uses this type of method for getting help anyway? Aren't the days of Bulletin Board BBS's gone?

People who know how to concisely ask a question, mostly.

Kill sendmail, postfix, exim, qmail, or whatever else you've got 
running.  One thing to be clear on is that Zimbra changes a LOT on your 
box; that's why in production I've always run it within its own VM, so 
it can break anything it likes without affecting anything I care about.

Yup.  It does.  But you need to kill any other MTA first.

The Zimbra setup guide is very clear about this-- how did you get this 
far along without referencing it?
