OK, I will take it out of 1.997.
Do you guys want "unknown" or "none" to occur for NXDOMAIN?
I view SPF as returning information about the probability that sending
email to the return-path address will actually reach the sender of the
message.
In this view, if the sender's domain does not exist, then there is no
chance that sending email to that address will work. Hence the rationale
for 'fail'. As has already been noted, most MTAs already reject mail if
the sender's domain does not exist. Also note that the check is MSQ for
the existence of the domain does not cost anything -- the DNS lookup has
to be made to do normal SPF processing.
The whole HELO thing is another story -- and I don't really care what is
returned in that case.
