Re: [PLUG] Need help with Postfix config

I agree that SMTP auth on an alternate port is a good thing, especially
since ISPs are blocking 25 outgoing more these days. However, Port 587 is
the standard port for accepting mail from users.

You should be able to configure it to accept authenticated users on both
ports without causing a problem, which may help reduce support.

I can't help you specifically set it up, but the commands postconf and
postconf -n should be helpful if you havent used them yet.
