OK, i have posfix installed and configured on the webserver (according
to the mailman doc). When i send a test message to the list, i get a
undeliverable notice:

I have a dns entry that points to the webserver and a mx record that
points to the webserver. I just thought of something that might be
causing the problem: the "real" mail server serves the virtual domain
that the list also is for. It appears all mail is going to that
mailserver and the user does not exist on the mailserver. Just in case,
i have a skype, aim and yahoo IM account.
