True, but so what?  If you want to do a DMARC alignment check, you do it 
the same way as for any other domain.  For the umpteenth time, DMARC is 
not the magic anti-spam bullet, and you continue to use whatever other 
filtering methods you use.

> Would that add clarity?

No.  Let's close #112 and talk about something else.
