- The current ugly "kissing cousin protocol" SRS is not part of
the package, so those with forwarding issues that they know
are real for their system, can only use a neutral/softfail.
Forwarding issues are a problem for receivers. Senders can't possibly
know about forwarders - because the receiver sets them up! By the above
logic, senders can never use -all unless they discover all the forwarders
configured by all potential recipients - and track them in real time.
I've tried to stay "neutral" (excused the pun) on the blame issue because I do
support SPF, but since you forced the issue, I will take a stance.
The problem is the protcol for both the SENDER and the RECEIVER. SPF was
introduced with a PARTIAL solution to close one loophole and workaround with to
address the problem it couldn't address by introduced MORE loopholes.
Forwarding is just one problem. Authorized MUA Aliasing is also a BIG real
problem for SPF.
Thats a protocol problem when you attempt to join into the solution spectrum
and only come out with with a partial solution and a potential for breaking
currently working operations.
Administrative disciplines will mostly disgree, but we are talking about a
technical principle only technical disciplines can better understand. The
former wishes to dictate POLICY and OPERATIONS over technical mechanical
considerations. The latter thinks in terms of logic and automation with a
disregard towards policy. The two do not mix very well, ergo CONFLICTS.
