I was trying to upgrade our Zimbra server last night (not a Zimbra upgrade, a hardware upgrade; I was doing a lateral move from one 4.5.11 to another). It looked like all went well when I fired up the new zimbra server, every component appeared to start based on the zmcontrol start messages. All of the mail that had queued up at our border mail server soon noticed that our mail server was back online, and the new server's mta quickly received about two hours worth of deferred mail. Meanwhile I opened a web browser and the first sign of trouble was that nothing appeared to be listening on ports 80 or 443.

While investigating further I noticed Zimbra was not delivering the mail - the mta was receiving, but lmtp was giving connection refused. zmcontrol status showed that tomcat was not running. (I am still working on why that is the case, but that's actually not what I need help with at the moment.) After an hour of working on a fix I needed to get mail working again, so I shut down the new server and put the old server back in service.

The problem now is that two hours worth of our mail is in the deferred queue on the new server, and I am trying to figure out a plan to rescue it. Does anyone know how I might approach this? Thanks.
