Shutdown and backed up zimbra 5.0.16, followed directions in release notes to 188.8.131.52 - no errors reported as you can see in the logs, and everything works except for the mail transport. I can not send or receive email. Can anyone figure this one out as this is my 2nd attempt to upgrade zimbra 5.0.16 to a newer version. First attempt to upgrade gave the same result with no mail transport and that was to version 6.0.6
Any help or pointers will be welcomed.
