[Mailman-Users] urgent: list sends lots of email to list-admin

[Rudy Gevaert]

Hi,

Yesterday a list send a lot of mails to the list-admin.  2/3 per
second sometimes.  Now my mail access has been cut of due to that
(what's normal).  What could the problem be?  The installation has run
without trouble for over a year.

I'm using exim and the mailman in Debian Stable

Relevant logs:

a bit later (no logs with guk in during 10 minutes):

mail from "guk": note: nobody sent to guk!

2004-03-17 17:24:12 1B3dq0-0006vo-00 <= guk at student.UGent.be U=guk P=local S=468

sends mail to list admin:

ok

and guk sends again a lot of mails:

and that goes on... and on...

What could be caussing this?

Thanks in advance,
