But I don't have a static IP, and we're talking Sympatico here... ;-)
It's against my TOS to even run a mail server (of course, I can run a
P2P server and upload GB's of pr0n, *that's* no problem...).

On my end, Postfix is configured to send mail *only* for "host":

mynetworks_style = host

but I could configure it like so:

#mynetworks_style = subnet

so no one outside my router would be able to use it as a relay, right?

Like I say, I'm currently on a dynamic IP, so I'm not even sure that's
possible. I use Zoneedit.com, which has a field where I can enter a
mailserver name...is that an MX record?

Sheesh, just when I think I've got a grasp on things, I realize how much
I have yet to learn...:-P

Thanks for the reply, I'm learning slowly, but I'm learnin'!
