[Mailman-Users] Subscribers request rejected - host relay problem

[Mario Bertrand]

Hi all,

I have a mail reject problem and can't figure out how to fix it.

Here is the reject log of exim:

1999-08-13 07:18:52 refused relay (host_accept_relay) to
<subscriber at host.com> from <listname-request at tbrq.org> H=localhost
(tbrq.org) [127.0.0.1] (www-data) 

Thanks for any help

Mario B.
