I am running CentOS 4, Zimbra 4.5.3 -> upgraded to 4.5.5. After the power loss fsck reported quite a few filesystem errors (I had to fix in single user mode).
I could not upgrade to 4.5.5 very easily, I ended up changing my LDAP password in addition to manually starting slapd during the upgrade process so it would load my settings properly. In the end, I was able to complete the upgrade without any errors on the screen.
After the upgrade completed, things worked a bit more but I'm still having problems. Most importantly all of my incoming mail is being deferred.
My box resolves properly (editted). I have an internal DNS server that resolves the zimbra machine to a local IP but the rest of the world sees the IP that is in front of the firewall.
[root@email log]# dig email.hostname.com

email.hostname.com. 86400 IN A 192.168.1.33
Here is the error I am seeing two different errors depending on what my hostname is:
While hostname is "email":
postfix/qmgr: 62C3613B59C: to=
, relay=none, delay=0, status=deferred (delivery temporarily suspended: lost connection with email.hostname.com[192.168.1.33] while sending end of data -- message may be sent more than once)
While hostname is "email.hostname.com"
postfix/qmgr: 4C91C13B5C9: to=
, relay=none, delay=0, status=deferred (delivery temporarily suspended: connect to email.hostname.com[192.168.1.33]: Connection refused)
After a restart I caught this in my zimbra.log
postfix/postqueue: fatal: Queue report unavailable - mail system is down
However zmcontrol status shows:
[zimbra@email bin]$ zmcontrol status
