Tony, that's very useful information. 

I imagine for people who don't know, you're using postfix but use it as
a drop in replacement for sendmail? So, you're using the postfix to
sendmail compatibility interface? For the sake of compatibility with
applications that look for sendmail by default or whatever?

I'm guessing, but your campus server requires authentication and that's
not a problem because you're not blindly relaying. Correct?

So, our server requires reverse DNS or it won't accept mail. Individuals
without that who simply use localhost as their smtp would have a
problem. To use postfix as you do, people would need what?

(Thanks in advance for the information. :)
