Newton
Do you appreciate the difference between a HELO check vs. a
MAILFROM/PRA/SUBMITTER check?
Yes
Do you understand the semantic differences between a CSV check on
HELO and an SPF/Sender-ID check on HELO?
No. I have found this thread very muddled and difficult to follow. As
far as I can tell this has not been stated clearly.
Is it clear to you that CSV has definite security advantages over
SPF/Sender-ID?
No.
In general it would be helpful if semantics and requirements for
semantics were explored prior to discussions of syntax or encoding.
Margaret.
