Mr. Rollyson,

Do you have any data to justify such a claim regarding filtering of email using
an empty MAIL FROM 2821 header as a parameter in an automated decision making
process?

I would be very curious to see any data that you have on this subject to support
your claim. I am sure the ASRG group would find such data to be extremely
useful.

Cheers!
