Hi! I'll answer what I can and others will chime in, I'm sure. If you're
pretty sure that you're ready for the ISP to forward, then you can check a
couple of things first.

1. telnet to your mail.myserver.com on port 25. Do this by typing telnet
at a DOS prompt. Then type open mail.myserver.com 25. Substititue your
info. You should get a reply from your mail server internally. That only
proves that internal email will work.
2. If you have a router, port 25 must be opened and forwarding to your
server's external nic if you're using two nics.

You mentioned www and email, are you hosting your own external web site? If
so, you need other ports open that make me nervous.

Hope that gets you started.
