Did you upgrade to Mailman 2.1.18-1?

Look at the messages received from the list. If this is Mailman 2.1.18-1
and dmarc_moderation_action and/or from_is_list is Munge From and
reply_goes_to_list is Poster, there should be a Reply-To: header with
the original poster's address. If this is the case, and a simple 'reply'
includes addresses such as the list posting address which aren't in the
Reply-To:, then the fault is with the MUA doing the replying.

Both RFCs 2822 and 5322 (sec 3.6.2) say:

   The originator fields also provide the information required when
   replying to a message.  When the "Reply-To:" field is present, it
   indicates the mailbox(es) to which the author of the message suggests
   that replies be sent.  In the absence of the "Reply-To:" field,
   replies SHOULD by default be sent to the mailbox(es) specified in the
   "From:" field unless otherwise specified by the person composing the

RFC 822 (still the actual standard) sec 4.4.4 says in part:

        For systems which automatically  generate  address  lists  for
        replies to messages, the following recommendations are made:
            o   If the "Reply-To" field exists, then the reply  should
                go to the addresses indicated in that field and not to
                the address(es) indicated in the "From" field.
