First of all the subject of this thread is an incorrect assumption.

AccuTechnology can include an alternative embodiment in an analog circuit.

That is intentional.

But you are way off target below.

Please read our web page again.  We state clearly that is not part of 
AccuTechnology.

Yes this is superior method, but some MTA (e.g. AOL) take it but bounce later.

Agreed.

I see the same messages from non-existent and existent senders.

That is an example that I am contributing and not withholding helpful knowledge.

You are conflating.  You can train on non-existent senders, but remove them 
from your performance measurements.

NO.

I am against trivial method patents which stifle software innovation:

Sorry but that lack of technical detail on our web site about the patent is 
intentional for now.
