Thanks for the reply. I am not seeing that. The From: looks like this:

That must be a RedHat thing having to do with their backport of DMARC mitigations. If you don't like it, install from source.
In "General Options" for that list I set the item "Replace the From: header address with the list's posting address to mitigate issues stemming from the original From: domain's DMARC or similar policies." with "Munge From." Did I set the wrong thing?
That will apply From: munging to all posts. I have no idea what the RedHat package does, but if in Privacy options... -> Sender filters you have dmarc_moderation_action and dmarc_quarantine_moderation_action set General Options -> from_is_list to No and set dmarc_moderation_action to Munge From and dmarc_quarantine_moderation_action to Yes and if you have it, dmarc_none_moderation_action to No.
This will apply From: munging only to those messages From: a domain that publishes DMARC policy = reject or quarantine.
Hi Mark,
I didn't realize that there were OS dependencies in the DMARC mitigation. I thought it was all within the mailman code.
In any case I'll look through those options and see what they do in RHEL. Thanks.
