In the typical configuration, only those folks who are
connecting from "off campus" need to configure SMTP AUTH;
the people who are sending mail from the provider's network
don't need to do it.

I hear large providers are moving toward SMTP AUTH: for
example, Bellsouth
http://www.dslreports.com/forum/remark,10485779 and I have
heard Interland is doing it too.

Some people are interested in a very restrictive SMTP AUTH
as a way to enable + versus ? for shared outbound servers.

Most people are interested in being able to do SMTP AUTH at
all so they can connect back to their ISP's MTAs even when
they're roaming at a place that blocks or hijacks port 25.
