Not sure why i'm having so much trouble getting Zimbra set up and working but i'm still not able to use it after futzing with it pretty much all day, right now email is always rejected or deferred by postfix:

to=, relay=none, delay=0, status=bounced (Host or domain name not found. Name service error for name=localhost.localdomain type=A: Host not found)

Is it true that postfix config files must be edited manually and aren't updated by adding a new domain in the administration screen?

Any suggestions about how to get started in the right direction would be much appreciated.


P.S. Does Zimba set the system clock at all? Ever since installing it my system clock keeps getting reset to the incorrect time, no matter how often I correct it.
