Is your ISP blocking outgoing port 25?

Outlook supports Automatic Account Configuration, but unfortunately it seems
to be only for Outlook, not OE or WM.

It's a pity that MAAWG or another group hasn't written a specification for
the automatic downloading of configuration (with certificates, to be sure,
for some kind of repudiation) and the update thereof, for adoption by the
leading consumer e-mail clients.

Better yet would be for the MUA to probe for the "best" configuration. 
Setting up mail is a royal PITA even if you know what you're doing. And a
near death 
experience if you don't.
