What is "mail.host.com" and where it is located? For example, is it a DMZ
server of yours on its own interface, using port-forwarding from the router?
Is it your ISP's mail forwarder? Is it the router itself? Is it an off-LAN
mail server at another site run by your company? Or is it something else?

Is it the same machine from which the LAN clients receive their POP3 mail?
If so, does the POP3 access program also use "mail.host.com" to identify the
server, or something else?

If you tell the SMTP client (which one is it, BTW?) to find the SMTP server
by its actual IP address, does that do any better? Or can you telnet to its
port 25 if you use its actual IP address?

If it is your machine ... what OS does it run and what SMTP server package?
Is it set up to do DNS resolution properly? Can the SMTP server telnet to
its own port 25 successfully?

If it is your ISP's machine ... does it require any authentication before
accepting SMTP traffic for forwarding?
