PRA is not a magic new "entity" in the system. It is just a terminology for
checking existing headers, if any, at the payload.
True, but PRA is not a specific existing header - it is one of the
existing rfc822 headers selected according to a patented algorithm.
SPF1 means checking MFROM.
Correct. (Except it can also check HELO.)
By stating they will not do a MFROM check, it could only mean they are
delaying the check until the payload is received. They will need to check
for the Return-Path: which is the MFROM.
No, they do not check Return-Path. They check From:, Sender:, Reply-To:,
or one of the other rfc2822 headers selected according to their algorithm.
I don't believe Return-Path is selected by their algorithm.
They are checking a COMPLETELY DIFFERENT identity than MFROM. Their
new identity might have some value, but it is not MFROM.
