[Mailman-Users] no delivery of list postings

[Fabian Linzberger]

Hi!

I am running a debian potato server using apache as webserver and exim
as mta. I have installed mailman 2.0.6 according to the instructions
found on www.list.org also I added configurations for exim according to
the exim/mailman howto, the tests on the bottom of the howto all worked
fine.

We have several domain names pointing to this server: the main host name
is granul.at, whereas the one that is used to access mailman lists is
slp.at.

All the Webpages and scripts seem to work fine (I can create a test
list, subscribe people to it, they get a welcome message, listinfo is
there...), however if I post a message to the list or list-admin it
disappears without further notice. The mailman logs are empty and exim
only says:

2001-08-28 06:20:40 15binG-0004M7-00 => test2 <test2-admin at granul.at>
D=list_admin_dire
ctor T=list_admin_transport
2001-08-28 06:20:40 15binG-0004M7-00 Completed

(the same without admin for the list posting case)
There is no further delivery to any real-adresses...

This also happens regardless of posting to test at slp.at or test at granul.at
(test beeing the list name).


I assume there is some problem with the director or transport, since
this is the last trace that my messages leave before disappearing...


I have included the exim.conf and slp.at.aliases file for your
reference.

If you need other info, please tell me and I will try to provide it.


thanks a lot
Fabian

another host with dialup connection using fetchmail to deliver most

problem since nothing changes if I comment it out...)
