I just installed a sonicwall pro 100 on my SBS 2000 network. I have no
problems sending email or accessing the internet. Our web server and email
server are on the same machine. Our web server is accessible from the
internet so I know port 80 is open. But we still can't receive email.

I created a rule to allow traffic from the internet to the LAN, but I still
get the same result (No Email).

Is this a DNS issue involving the MX record for the mail server?

Any ideas how I can resolve this?

Thanx for any input!
Jeff
