[vox-tech] Mutt and SMTP server

[Ken Bloom]

My computer is currently for mutt to send outgoing messages using 
Postfix (I haven't made any config changes to postfix from the default 
mandrake install) This setup worked just fine for me at UC Davis over 
the school year, when I was on resnet, but now I'm using dialup through 
EarthLink over the summer, and I can't seem to send any messages through.

How does one configure mutt or postfix to try to use smtp.ucdavis.edu to 
send outgoing messages?
