[Mailman-Users] Wrong email addresses leading to mail-loops

[Michael Dosser]

Hello dear list members!

We were running mailman 2.02beta and moved to new a new server (FreeBSD 
4.3-STABLE, sendmail 8.11.4 and mailman 2.03). all lists are working fine.

Problem description:
Whenever a members email address is wrong, e.g. bla at .bla.org or whenever a local
email adress has no mailbox qrunner tries to deliver x-times to all members,
which it has reached until the wrong email address. It obviously stops when we
delete the files in $MAILMANHOME/qfiles. But this cannot be the solution since
nobody is sitting there watching postmaster mails every second ;)
Anyway: this is very annoying since lots of members unsubscribed after this 
has happened ... uhm, and: yes, we have bounce options activated on every list
with the options: "5","3","5","disable and notify me". Secound uhm: yes, I
searched the archive, but have not found anything similar.

Question:
Is this a bug in mailman 2.03 or did i make some configuration errors?

If the latter is the case, I added the servers configuration below, hope that's
not to much ...

Settings:

mm_cfg.py:

DEFAULT_HOST_NAME = 'mailman.domain.bla'
DEFAULT_URL       = 'http://mailman.domain.bla/mailman/'
MAILMAN_OWNER     = 'mailman-owner at xxx.xxx'
PUBLIC_ARCHIVE_URL = '/pipermail'
PRIVATE_ARCHIVE_URL = '/mailman/private'
MAX_SPAWNS        = 100
SMTP_MAX_RCPTS = 100
DELIVERY_MODULE = 'Sendmail'
SENDMAIL_CMD = '/usr/sbin/sendmail'

Sendmail:

First looks up the virtusertable and maps then to aliases. All local users
have a virtusertable entry and for every domain we have we put a
@domain.bla error:nouser User unknown
We have cyrus as the local delivery agent.
