Yeah, I've no clue why this works. I had set up a qmailtoaster for a
small biz before sbcglobal took over and it's been runnning with that
configuration perfectly all this time.
Thanks,

I don't know why mail.pacbell.net lets me do this, but your advice worked
perfectly. You just ended three days of googling on this subject.
Thank you very much,
They do something similar to RoadRunner. Almost. All traffic on port
25 is forced to their mail server, or it doesn't make it out of their
network. This is to stop spammers from setting up mass-emailers on
their network, or zombies infected from doing the same thing. They
allow you to send through their email servers, as long as you're on
their network (one of their IP addresses). If they see that you're
spamming through them, they shut you down. Not exactly a fix to the
problem, but it is *A* solution. Until something like SPF (which is
full of holes itself) goes into effect, there's no real way to stop
spam, so companies that offer Internet access are scrambling and
knee-jerking to stop it. One of the problems I've run into is that I
have a lot of mobile users - they send emails from hotels, airports,
hotspots, etc. Most of these are blocking port 25 to outside sources as
well (funny story - there was a spammer running a mail server within an
airport in Dallas from his laptop... Just paid for parking and mailed
away!), so I've had to add a firewall rule to forward port (as an
example) 9921 to port 25 so that my roaming users could still send
emails through the company server.
