Messages released from Barracuda quarantine won't show up

[meltingrobot]

I am having a weird issue where when I release messages from our Barracuda spam firewall, they never show up on the Zimbra mail server. When I look at the log files, I can see everything in the log showing a successful delivery, but the message never arrives. It's really odd because the Barracuda is relaying regular mail just fine without any problems. And I see that it is making the connection and relaying messages released from quarantine fine. I even see where the messages pass through ClamAV as CLEAN in the log file. I just don't know what is happening to the actual message.

Here is what I am seeing in the logs that looks like the message is successfully being delivered, I changed names/IP's of course.
