My isp (bellsouth) is block all outbound port 25 connections and requiring that outgoing mail use their mailserver, which apparently requires AUTH. I am really trying to get two things to work, one probably much easier.

1. I am trying to write a script capable of sending me unattended emails from the command line. I was trying to use ssmtp, but it's seeing some "520 Command disabled locally" error on attempting to do AUTH. Normal (MS Outlook, Thunderbird, Evolution) mail clients work fine with AUTH on this server. How can I send mail from the command line with the proper AUTH?

2. I'd really like to have a local SMTP "server" that just auths with the upstream/ISP server and sends things on. In other words, I'd like PHP's mail() function to work.

I'm not worried about local delivery of messages at this time, just getting mail off the system.
