I've been using Unix and the Internet for over twenty-two years, a 
professional Unix system administrator for over seventeen years, and 
specializing in managing Internet e-mail systems for over fourteen 

Congratulations, this is a first -- I don't recall having ever seen 
this particular error message before in my life.  And at this stage 
in my career, I don't get too many of those.

This is almost certainly a problem in your local MTA, where Mailman 
is unable to hand off messages to the mail server for some reason.

What MTA are you using -- is it Exim?  How is that configured?  Have 
you checked the MTA logs, to see what it says about this issue?  Have 
you checked to make sure that your DNS is configured correctly?

Have you checked the relevant FAQ entries regarding MTA problems and 
non-delivery issues?

Have you checked your MTA configuration to make sure that it is 
turning off all anti-spam/anti-virus checks for all outbound 
messages, as suggested in the FAQ?  If you can't do that, can you at 
least confirm that your anti-virus scanning system is working

Trend Micro has announced that they will cancel the stop.mail-abuse.org
mail forwarding service as of 15 November 2006.  If you have an old
e-mail account for me at this domain, please make sure you correct that
with the current address.
