It is the From: header that had be rewritten by Mailman
when getting messages from domain with DMARC policy set to reject.
( example given:   yahoo.com )
The test showed it wasn't rewritten. :-(

The version of Mailman that Syslinux is using should be able to do
it. Why it doesn't, is unclear to me. ( I don't have shell access to
the involved server ) Neither I don't have the power to order further
research on what is going on.

I can only ask for further for research why Mailman is not acting
upon 'dmarc_moderation_action' settings.



@Patrick: Thank you for the good test data. Due the fact that
you Cc-ed me, I could compare what sent direct to me and what
got through the mailinglist. ( No From header munging, both
where Content-Type: 7bit )
