I've recently been hearing that some subscribers to a club mailing list who use
gmail are having all messages pushed to their spam folder. One user said it's
only an issue when the sender is a gmail user as well. I'm running mailman
2.1.23 and had dmarc_moderation_action set to the default value..which I think
was Accept. I recently changed it to "Munge From". The
dmarc_quarantine_moderation_action is set to yes, and
dmarc_none_moderation_action is No. When using the old settings gmail listed
messgaes as: SPF PASS, DKIM "Neutral with domain null", and DMARC FAIL, but
when a non-gmail user sent a message the DMARC was not listed.
After changing to "Munge From" it still has a DMARC fail. What are the
differences that I should be seeing after changing the dmarc_moderation_action?
Here is an authentication header of a message from a gmail user to a gmail user.
ARC-Authentication-Results: i=1; mx.google.com;
dkim=neutral (body hash did not verify) header.i=@gmail.com
header.b=dAmiQOEo;
spf=pass (google.com: domain of bockbrew-boun...@lists.bockbrew.com
designates 65.181.121.110 as permitted sender)
smtp.mailfrom=bockbrew-boun...@lists.bockbrew.com;
dmarc=fail (p=NONE sp=NONE dis=NONE) header.from=gmail.com
Thanks for any help,Kevin Nowaczyk
