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'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

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.
