  for mailing lists, the topic of DKIM is complicated, it's not just
about outgoing email.  It saddens me if Remi's ISP free.fr goes as far
as assuming emails without DKIM are spam, but I believe this is still
quite uncommon and none of us probably has time to start fiddling with
this either.

  I just tried to enable this, even though the action taken is mildly
horrifying for me - hopefully it will indeed happen only to emails from
DMARC-reject domains.  Thanks for the pointer!

It's been a while since I looked at this in depth, but the problem seems
to be that it modifies the email but doesn't strip the original DKIM,
which then fails to validate. Even adding a DKIM from the mailinglist
wouldn't help, because in Patricks' case, his domain has a stated DMARC
policy, which requires a valid DKIM from that same domain. It's the
DMARC that makes this so much worse as just failing DKIM isn't usually
enough to get classified as spam.

The list is on MailMan 2.1.18, which has support for working around this
problem:

Admin, can you try this dmarc_moderation_action = Munge From?

It is the mail server of this mailing list that is not well configured. Even my 
own messages are classified as spam for me now. The list does not send DKIM 
identification.

Patrick, for what it's worth, I think almost no-one will have seen your
email because laposte.net claims it's forged. Either your or
laposte.net's email server is mis-configured.
