DMARC unauthenticated mail is prohibited. (in reply to end of DATA
command)
You need to ensure your outgoing mail is DKIM signed by your domain and
you need to apply DMARC mitigations. These mitigations include the
General Options -> from_is_list setting and the Privacy options... ->
Sender filters -> dmarc_moderation_action setting.
The former of these was first implemented in Mailman 2.1.16 and the
latter in 2.1.18, although if your 2.1.15 is a vendor package, some of
this may have been backported.
Without DMARC mitigations, post from users in domains that publish DMARC
policies of reject will probably be bounced by any recipient ISPs that
check DMARC.
See the FAQ articles at https://wiki.list.org/x/17891458 and
https://wiki.list.org/x/17891477 for more information about DMARC.
