Been having some troubles with zimbra the past few days.

I have managed to get the web client back up and running although i cannot recevie any email.

the message i get back is
The following message to <REMOVED@DOMAIN> was undeliverable.
The reason for the problem:
5.1.0 - Unknown address error 554-'5.7.1 <REMOVED@DOMAIN>: Relay access denied'

When i do the zimbra status command i get the following output
mackhall@zimbra:~$ sudo -u zimbra /opt/zimbra/bin/zmcontrol status
