No, it's greylisting which is based on that idea and not the SMTP
implementation.
Well, I will argue that the successful growth of greylisting systems is
based on the fundamental SMTP 4yz retry principles. It that wasn't the
case, greylisting would not be a consideration.
I accept the idea that the client may not reissue the same ENV
information, but that is by far *not* the normal practice in retry
logics. Google would be the first that I know of,
Yahoo Groups did this 3 years ago. As far as I can tell they have
changed their practice (I can only speculate that the growing popularity
of greylisting caused too many failures).
