[Mailman-Users] mail server cannot communicate with mailman

[George Argyros]

Thank you for your answers.
I managed to make the outgoing mail of mailman to work with Exim. Now
password reminders, register confirmations etc are sended normally
from mailman.
However the incoming mails still cannot reach any mailing list,
although this time, the mail seems to be accepted by the Exim.
Additionally in the Exim mainlog i get the following error entry:
|/var/lib/mailman/mail/mailman owner foofoo <foofoo-owner@**********>
R=system_aliases defer (-30): pipe_transport unset in system_aliases
router
I' ve searched a bit in the internet, and i saw that this is a
relatively common error, however i didn't find any solutions.

In order to configure exim to work with mailman i followed the
instructions in the file /usr/share/doc/mailman/README.Exim4.Debian.
