I see the forwarding
problem and the DNS loading problem as being comparable in
importance. They have equal probability of killing SPF.
Forwarding can be and is handled using methods unrelated to the
specifics of the SPF spec.
That is, as a mail recipient, you have two options:
1. Ask your forwarders to do SRS.
2. If you do SPF tests, whitelist your forwarders.
Because these solutions are completely uncoupled with the SPF spec
itself, there is no need to delay spec publication on their account.
sooner SPF provides a solution, the less chance that SPF will have to
conform to some awkward external requirements.
These solutions to address forwarding have been provided since the
very beginnings of SPF, years ago.
