I created a pop box with our ISP in the meantime, and now I'm reconnected I have pop'ed those emails back down to the zimbra server. Mail has started flowing back in the normal way, however, I can not send emails. It was originally the 5.0.0GA version which had this problem, so I followed these steps to try and fix it. That didn't work, so I downloaded and installed 5.0.2. Still not working, but the error message I get now is a little more detailed:

Any ideas? Sending mail is a kinda handy feature I would like to have...

Can you send to local users at all? (ie: Sending mail to other people on your domain works ok, but not to the internet?)

Nope, can't even send to local users. All services appear to be running fine, and certs don't expire for another year....

I checked out the logs immediately after causing the exception, and the chained exceptions gave me the detail I needed - it couldn't resolve it's internet host name. A quick change to my local DNS server was all that was required - phew!
