The lsit messages is reinjected to Postfix, the queue ID is
127EB2A203E.

The message is delivered to a maildir store. I guess this is not a
Mailman problem, but a Postfix one. Perhaps you got address rewriting
wrong - is the mail really supposed to be delivered to
kozlowsm at alpha.mini.pw.edu.pl with the local(8) delivery agent? After
all, your mail address seems to be kozlowsm at mini.pw.edu.pl, without
the "alpha" part - but I don't know your mail setup.

When using a content_filter, you should make sure that you only do
virtual address rewriting once, i.e. either the main smtpd (or the one
you use for injecting messages generated by Mailman) _or_ the smtpd
used for reinjection from amavisd-new should have set
"receive_override_options=no_address_mappings" - only one, not both of
them, preferarbly the one used for reinjection from amavisd-new.

Anyways, this is getting off-topic.
