Hi all,

As one should see in the headers, the mailman installation got updated.
Although the used version back then already had patches regarding DMARC
backported. Anyway for now latest upstream (in the 2 release cycle) was
installed and will be tracked.

Can we verify whether this mitigated the problem for now?

But I still think doobry had a good analysis of the problem and I still
think that checking DMARC for emails sent over onionmx should be disabled.

They won't work as intended AND for emails over a mailinglist this is
now mitigated, because they face the problem also without onionmx and
had to adapt. But as soon as you expand these checks beyond your own
domain you will start to run into problems again for domains sent over
onionmx.
