Re: [Asrg] Verizon's asymmetrical anti-spam causing problems

It hath once been written:

The SAFEST return address for probes of that type would be a null sender 
<>, simply by virtue of it not generating a reply. However, some very 
misguided postmasters block support for null senders, which also 
effectively blocks bounce messages, without having any real impact on 
blocking spam.

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!
