No mail going Out

Hi all,

I have been running Zimbra for a few months now and everything has been slick. I recently upgrade and everything went smooth and has been running great. Except for today. I logged in to the Zimbra admin and it took days to load. I looked at my mail queues and I have about 10,100 emails in Incoming and about 10,100 emails in Active. I logged into the server and checked to make sure it could ping out to the internet and it can. I rebooted the server about 3 times, but the mail just keeps piling up. I have not really had to troubleshoot things on Zimbra since it has ran so smoothly so I'm not sure what commands to run to do what. Can anyone please give me a hand here?

What I would like to do is get those 20,400 emails in limbo out of the queues and put aside so I can see if email is really going out. Then slowly add back the emails. Can this be done?

I'm running the newest version of released Zimbra on Ubuntu Fesity Server.

Thank you all!

Is there a way I can from the console of the server, move all email from Incoming and Active to the Hold or Deferred area, since the web page is running like crap because the server is trying to process the 30,000 emails...??
