After my last system reboot, no messages are being delivered to the inboxes and no emails are being sent. After a little digging this is what I am seeing:

When I log into the admin console I see most of my email is being deferred. When I do a 'zmcontrol status' command I see this:

antispam Running
antivirus Stopped
zmclamdctl is not running
ldap Running
logger Running
mailbox Running
mta Running
snmp Running
spell Running

Any ideas?
