Hi Mark and all

That problem was solved, although not exactly according to
your instructions (see details below). I have another prob
at the bottom of this mail.

In this Debian fresh installation, there is user and group called 
list. The files in /var/lib/mailman itself is root:list,
files/directories inside have all sorts of ownerships:
root:root, list:list, root:list, list:klog, ???

Changing the ownership helped. Possibly not the best

Thanks. That was missing. I just bin/genaliases >>
/etc/aliases and ran newaliases.

That part is sofar OK.

The next question is the archives.

http://server/cgi-bin/mailman/listinfo brings me:

  Bug in Mailman version 2.1.9
  We're sorry, we hit a bug!
  Please inform the webmaster for this site of this problem.

/var/lib/mailman/log/error has amoung other things
file /usr/lib/mailman/Mailman/MailList.py line 595

Again permissions?
