AFAIK
SMTP does not use authentification, this is why you set pop before relay to
authenticate the user and allow them to send mail for a time period after
pop authentification.
You do of course need to have the user set up in the allow relay settings to
stop the server being an open relay for all, so this means that only
authorised domains are allowed to use smtp anyway.
This is a kind of authorisation I suppose.

Paul,

Just for your info, SMTP does do Authentication.  Take a look at the output
from my server.

I never personally setup SMTP authentication, but it appears Cobalt put all
of the hooks into it.
You can go to www.sendmail.org, and do a search for it.  I know for a fact
that there are some
detailed how-tos.  I have looked into it, but I never felt like actually
doing it.  It does take
some time.  But Allen is right, if you set it up, you do NOT need to do Pop
b4 SMTP, or access
lists, which makes it really nice.  Yahoo! Use to, and I think, still does
SMTP Authentication
(take a look at your email client, it should be built it!)
