[Mailman-Users] Problems with my domain

[Michael Rose]

Hi,

I was wondering if anyone could help me with a problem I am having.  When
we send mail out using Mailman, the mail is only delivered to those with a
domain of ag.arizona.edu.  When I checked the smtp-failures file in my log
directory, I got the following message, many times.  This example is just
from someone with the domain "u.arizona.edu" which are our primary users
besides those with "ag.arizona.edu".  

Sep 15 20:10:11 1999 TrySMTPDelivery: To xxxxxx at u.arizona.edu:
Sep 15 20:10:11 1999 TrySMTPDelivery:
Mailman.pythonlib.smtplib.SMTPRecipient
sRefused  / {'xxxxxx at u.arizona.edu': (550, '<xxxxxx at u.arizona.edu>... we do
not
relay')}  (dequeued)

This message is shown with more than just people with domains
"u.arizona.edu", there is also problems with "aol.com", etc.  If anybody
has any information that would help me solve this problem, I would greatly
appreciate it.  Thank-you.
