FWIW,  here's a list of the DNs of subscriber addresses that got
unsubscribed last week from one of FMP's lists, ostensibly as a result
of the DMARC issue:

yahoo.com
hotmail.com
comcast.net
bellsouth.net
att.net
cityofgastonia.com
fronteirnet.net
sbcglobal.net

There were about 76 addresses, most of which were yahoo.com or
comcast.net addresses, with bellsouth.net coming in 3rd.
