[Mailman-Users] newbie: mailmain relaying denied

[JASON NOLAN]

Hello, this is my first post, and I'm a bit stumped, so I hope this is an
easy question to answer.

I've set up majordomo before, so I'm not totally clueless, but after
setting up mailman and going through the motions of starting a list nothing
happened. But I found this. This is obviously not a mailman error, but a
sendmail config error. But everything looks right on my machine, and I
can't figure out what the problem is.

Mailman.pythonlib.smtplib.SMTPRecipientsRefused  / {'realuser at utoronto.ca':
(550, '<realuser at utoronto.ca>... Relaying denied')}  (dequeued)

Anything I'm missing that is keeping the postman from delivering?

Thanks in advance for any thoughts,
