Hi All,
I'm using my FC4 box as a mail server (and also running Mailman).
It's starting to look like I may need to open up the SMTP server to
"outside access".
Since I don't want to become a SPAM gateway, I'd like to restrict access
to just a few people. But, there's a catch.
Some of my "customers" uses a dial-up connection and aways appears from
a different IP address every time they connect. So adding them to the
allow/deny list could be tricky.
How do I get the SMTP require a password? And, is that secure enough to
keep spammer's from using my mail server?
Thanks!
Jon
