Yep, Anton posts from  They publish a DMARC policy that
breaks mailing lists.  The best thing we can do is to do the above
rewrite of the From header.

The alternative is that all our Yahoo, Gmail and Hotmail subscribers
(at least) would bounce the email.

So this rewriting will happen for any From: line that has an address
that has such a DMARC policy.  We have had posts from Yahoo subscribers
bounced in the past.
