 .I don't think that this is a problem with Mailman.  The best way
 .to test this is by sending mail to the fully-qualified address
 .and seeing if it changes in the To: header.  If it stays the way
 .that you typed it, then you're just dealing with a simple case of
 .RFC 822 compliance.

The address stays as the sender typed it. What does RFC 822 compliance imply?

 .If you're using a different MTA, tough noogies.  I haven't played
 .with them enough to know how to deal with this.  :)

Smail is the MTA on the site Mailman should be running.
Sysdamin told me that relaying restrictions have been very strictly set after
a dangerous attack by unknown intruders. 

Anybody found himself in a simillar situation?

thanks
