I can relate to Mr. McDonald, telling a few non-technical users to make sure
"use username and password" is checked is nowhere near as you make it sound.
Many most likely don't even know how to get into their mail settings.
Pop-before-smtp might save you a lot of trouble. It's a small program to
auto-populate and remove (after a set time) IP's from a separate sendmail
access DB that are pulled from the pop authentication logfile. That way, as
long as a user has popped mail within 15 minutes or so, they are OK to send
through the server.
Karan's repo (http://centos.karan.org/) has a package built from Fedora
Extras.
