I have Zimbra installed on a server powered by Nginx. Since Nginx is on port 80, I placed Zimbra on port 8081. It worked for a few seconds, and I've been troubleshooting this for hours. Now, I just need a pair of fresh eyes to help me see what I am missing. Please see below:

Code:
zimbra@host366:~$ zmcontrol status
Host host366.mulyoo.net
	antispam                Running
	antivirus               Running
	ldap                    Running
	logger                  Running
	mailbox                 Stopped
		zmmailboxdctl is not running.
	mta                     Running
	snmp                    Running
	spell                   Running
	stats                   Running
	zmconfigd               Running
