[Mailman-Users] General Response Error... user not found...

[rjones at email.unc.edu]

I am running into the error below when trying to send messages to lists 
on my server... Basically, it returns that no user is found. Any ideas 
on what is going wrong? Any help would be much appreciated.

Thanks a million.
