Thanks to my hosting company restarting the VM Server, my VM got restarted and ever since Zimbra hasn't worked.
It was working fine up to this point.

I've tried the fixperms, erm, fix that has been mentioned, but it didn't have any effect.

Any help would be appreciated, my mail server is down and I don't have a clue how to get it back again now.
