This has nothing to do with mailman, it is a postfix configuration
issue. Postfix can be configured to reject mail if the receipient is not
local. You have this configuration setting in effect. I suspect your
problem is that you don't include $alias_maps in the
local_recipient_maps parameter in postfix's main.cf. This is very
clearly documented in the comments in main.cf and the
LOCAL_RECIPIENTS_README file that is part of the postfix distribution
and available on www.postfix.org. You need the alias_maps because that
is where you've defined mailman's email addresses.
