Thanks, Mark.
WRT Content filtering -- if filter_content is set to NO, then nothing else in
that section should apply, right? That is, even if there is stuff defined for
pass_mime_types and filter_filename_extensions?
Thanks,

If the message in the vette log is "Message discarded, msgid: <...>",
that message is only produced in standard Mailman by IncomingRunner when
a handler raises DiscardMessage. Again in standard Mailman, the only
Handlers that do that are:
MimeDel
- content filtering removes the entire message and filter_action is
other than Reject
Moderate
- a post is from a moderated member with member_moderation_action Discard
- a post is from a non-member in discard_these_nonmembers or with
generic_nonmember_action Discard
Scrubber
- if the top level MIME type is text/html and ARCHIVE_HTML_SANITIZER =
0 (not the default, and this only applies if scrub_nondigest is Yes)
SpamDetect
- when a message matches KNOWN_SPAMMERS
- A post is From: a domain with DMARC p=reject (or maybe quarantine)
and dmarc_moderation_action is Discard
- a message matches header_filter_rules with Discard action or with
Reject action and the message is to -owner
This is the current complete list for standard GNU Mailman. It is
essentially the same as in the old post with the addition of
dmarc_moderation_action. If your Mailman is from a downstream package or
has local mods, you can
grep -r DiscardMessage /path/to/Mailman/Handlers
to see if there are others
