Unable to send/receive mail after publish on isa2k4...

I get the following error when trying to send mail from a server
recently published in ISA2k4:

This is an automatically generated Delivery Status Notification.
THIS IS A WARNING MESSAGE ONLY.
YOU DO NOT NEED TO RESEND YOUR MESSAGE.
Delivery to the following recipients has been delayed.
       marvinc@xxxxxxxxx

I don't get any responses when trying to send to this server from the
outside. There are no errors being generated on the exchange server
and the following error was received from the Connectivity Verifier on
the ISA server:

The connectivity verifier "server" reported an error when trying to
connect to "ip address". Reason: No connection.

That was over an hour ago. I've since then rebooted and the error
hasn't returned. I've forwarded port 25 on the router but I still see
messages sitting in the que. I have a policy rule in place to allow
DNS and SMTP on the mail server and SMTP server on the external
listener.
What else could I be missing? 

The domain in question is mail.nusolutions.biz and I'm hosting the
mail server internally using TZO.

thnks
