[Mozilla Enterprise] ESR mailing list forwarding gives rise to DMARC "failures"

[Paul Kosinski]

Thanks Mike.

It's been about a week and things are working smoothly from my vantage
point -- no more DMARC "forensic" reports.

P.S. I had started to set up a subdomain just for Mozilla with different
DMARC settings, but it kept getting more and more complicated (both DNS
and Postfix mods). Your fix came just in time to spare me from also
having to modify our DKIM to deal with an email source subdomain (which
we never had before).
