Kevin,
Thanks for your reply. I'm following up to you privately since this may get
very specific to my situation.
I should explain exactly what my situation is. My server is connected to the
internet via a cablemodem to my ISP via eth0. I use eth1 to connect to my
internal network. For the purposes of my internal network, I use a bogus
domainname. I NAT my internet connection to the ISP and use dyndns to make
associate a domainname name with the dynamic IP address assigned by the ISP.

I assume that the SMART_HOST will point to my ISP's smtp server. But how
will the email indicate who it's sender was? Will it say
'[EMAIL PROTECTED]' or '[EMAIL PROTECTED]'? Either way, how will the
email make its back to me if someone simply tries to reply it?

Nope. My ISP actually blocks the smtp port to prevent commercial users from
trying to run a business over a residential cable connection. I actually own
a domain name but I have to pay for an ISP to host it. I could host it
myself if I could handle the email.
Thanks for your help.
