The way to configure Mailman/Exim integration is discussed at
which contains a link to <http://www.exim.org/howto/mailman21.html>.

I don't know if you're talking about MAILMAN_GROUP in mm_cfg.py (which
you shouldn't change from the default) or MAILMAN_GROUP in your Exim
configuration or some Debian magic MAILMAN_GROUP to adjust the group
expected by the wrapper.

for a better understanding of group mismatch errors.

If the MAILMAN_GROUP=daemon you refer to above is in your Exim
configuration, that should be what you need, if it is properly
referenced by a 'group =' in your mailman transport, but in your case
you seem to be using aliases for mailman instead of a mailman router
and mailman transport, so the 'group = MAILMAN_GROUP' would be in the
address_pipe transport.

However, I recommend you configure exim per
<http://www.exim.org/howto/mailman21.html> and do away with mailman
aliases altogether.
