Hi all,

I'm new to zimbra and I don't know where to begin with this.

Code:
[zimbra@munich ~]$ zmhostname
mail.parts-unknown.org
[zimbra@munich ~]$ zmcontrol -v
Release 8.0.5_GA_5839.RHEL6_64_20130910123908 RHEL6_64 FOSS edition.

The web interface is refusing connections. I do not run a firewall. Here's the most recent portion of the access log:

There have been a few restarts. Contabo upgraded the hardware on this server and I moved /opt (including /opt/zimbra) onto its own disk, not so much for space considerations, but to spread out disk access load.

From what I can see, the httpd daemon is running:
