If the messages are reaching Mailman, they are being discarded.

Discards are logged in Mailman's vette log with the Message-ID of the
discarded message.

Discards can occur for these reasons:
1)Message From: a domain with a DMARC reject or quarantine policy and
dmarc_moderation_action = Discard.
2)Message matches a header_filter_rules rule with discard action.
3)Message from a moderated member and member_moderation_action = Discard.
4)Message from a non-member in discard_these_nonmembers or with
generic_nonmember_action = Discard.
5)Message empty after content filtering and filter_action = Discard.
6)If scrub_nondigest is Yes and mm_cfg.ARCHIVE_HTML_SANITIZER = 0 and
the message's Content-Type is text/html.

In your case, 2) seems most likely.
