Exchange 2007: Messages Stuck in Outbound Queue. No inbound messages

I use a third party to filter my inbound messages. We're not receiving any messages from the outside.

My outbound messages are stuck in the queue.

Any thoughts on where to start troubleshooting?

Thanks

Stop all third parties AV or any other software. And once restart Microsoft Transport Service.

Stopped AV - Restarting transport had no effect.
Finally getting error messages in my outbound queue:

Message 1:

DNS Query Failed

Message 2:
451 4.4.0 Primary target IP Address responded with: "421 4.2.1 Unable to connect" Attempted failover to alternate host, but that did not succeed.

Thanks

(not sure we have alternate host.

Create a test account with mailbox and run the incoming email test in the Microsoft test site.
See what that flags and post the errors here for more help.

On the properties of the Send connector there would be a server name is that valid.
