[Mailman-Users] Making a Case for Upgrading MailMan from 2.1.17

I was too hasty in sending out the prior message; actually there is a feature in 2.1.18 which I believe will help you with the issue you are having.

Prior to 2.1.18, the DMARC feature was activated on a per list basis, and was set for each member regardless of whether the sender's email provider had the DMARC set up on the domain.  With 2.1.18, you can set it up so the headers only get munged if the DMARC action on the domain is quarrentine or reject.  It is worth noting however that depending on how your host get Mailman, this feature may already be available.  For example, some RedHat packages prior to 2.1.18 already have this feature built into them.

Sorry about that.

If you download the tar package for the latest version, 2.1.22, the NEWS file will give a changelog of what has changed between the versions.  I don't believe a newer version would help you with the issue you are experiencing, however, as that is due to the way that Mailman handles messages which come from senders who's email operator publishes DMARC records for their domain.
