I have a client who is running a NT4 sp6a box with MS DNS running with Winproxy 3.0 firewall as well as Mdaemon 4 for emails. DNS has been correctly setup with the primary updating the slave accordingly. However clients behind the firewall can only receive and not send emails. I believe that DNS & tcp/ip could be corrupted. Any ideas?

First, is their email server behind the firewall? If it is, you'll need to configure a rule on the firewall to allow SMTP from the mailserver out through the external interface of the firewall.

I believe that you're running all these services onthe same machine, is that correct?
