This is a new Install,not an upgrade. zimbra is running just fine, I checked my /etc/hosts file,
127.0.0.1 localhost.localdomain localhost
142.25.97.33 jesseb.ca
142.25.97.33 mail.jesseb.ca
hostname of server is mail.jesseb.ca
mx records are pointing in the right direction, i do no have a split DNS setup i don't think. If you need to configure it manually i havent.
also
zmcontrol status shows everything running for mail.jesseb.ca
Cheers,
S.A.
