dmarc mitigation debug
Hi gang!
I have a list with
DMARC mitigation action "Replace From: with list address" DMARC Mitigate unconditionally "Yes".
But list posts still have the poster's From:, breaking DMARC. How can I debug this? For a start, I looked in my sqlite database. Changes on the web interface list settings seem to be correctly applied to the database. But I don't see a "munge_from" in the fields of a list in the database.

munge_from is not a field name. munge_from is a value = 1 of
DMARCMitigateAction which is stored in the dmarc_mitigate_action field.
See

There's really not any logging that would help with this unless there were some exception involved, but that would shunt the message, not deliver it.
What are the full headers of the post received from the list?

Hi Mark!
Thank you for getting back to me. I'm releaved it does not appear to be an RTFM case.
munge_fromis not a field name.munge_fromis a value = 1 of DMARCMitigateAction which is stored in the dmarc_mitigate_action field.
This is indeed set to 1.
What are the full headers of the post received from the list?
I have send you a full email to my list privately. If anyone else wants to see it, just reply to me privately.

The message you sent me has a properly munged From:. The From: is of the form
From: "<user's name> via <list name>" <list_address>
and there is an added Reply-To: containing the original From: value.
This is as expected.
