smtp auth (was Re: the importance of security)

[Kevin Shalla <kshalla () UIC EDU>]

I'm unfamiliar with smtp auth.  Does this mean that when the user tries to
send an email message that they are required to authenticate, and can only
send messages with a "from" address of that username to which they just
authenticated?  If so, this could make email a fairly secure
intra-university means of communication, correct?  Does anyone have a link
to beginner's background reading on this?
