Just thought I'd spit this out, on one of my servers I'm running an
unpatched stock qmail-smtpd on port 25, and another qmail-smtpd that has
been patched using the SMTP AUTH patch listed on qmail.org on seperate
port.. So I just tell people if they want to use SMTP AUTH to use the same
SMTP server on another port and that seems to work for me. Still pisses me
off that I have to do that though.
