The implementation of the DMARC policy change is not consistent, which makes being subscribers of the various email lists not so fun any more.

I am not yet using the mail app but am hopeful by the time I start using it, it will be working right.

In the meantime, since the bad guys have won again, the best thing we can do is create that signature.

Google only replaces the From when necessary for DMARC.  If a Yahoo user were 
to post to this list, you would see the message as coming from them via the 
list (it would say so in the sender's name) and the address in the From field 
would be that of the group.  I don't know for certain whether GG also destroys 
the sender's address in other header fields--I never checked that--but for 
Mailman lists with the DMARC patch, Mailman drops a copy of the poster's 
address in the Reply-To field, so you can still extract and use it.  In spite 
of this, Apple dropped the prompt asking whether or not you wanted to use the 
sender address when it detected that the reply address was likely to be a list 
posting address; I have no idea why.

As to DMARC in general, well, to be honest I'm a resigned supporter.  The fact 
is that unlike the web, email has no definite, identifiable, user-visible 
author address.  Yes, DMARC messes up mailing lists and spam (and the people 
who claim to save us from it) have won again, but we could live with the 
changes if we all made the best of it.

Cheers,
