      In find that http://mnforum.org/ is 404.  DNS Lookup says no A record 
(http://www.dnsstuff.com/tools/lookup.ch?name=mnforum.org&type=A)  On the 
other hand http://www.mnforum.org/ and 
http://mapnp.mnforum.org/mailman/listinfo/ are both working, and have an A 
record.  Fix this by adding the domain without the www to the name server 
and you should be good.

     If the sender domain does not resolve the mail server is probably 
rejecting the mail connection without accepting the mail.  I'm surprised 
you are not being rejected by more servers.
