Sounds like you followed it pretty well to me! Thanks! I think this is
exactly my problem. The offender is the University of Washington, and
they have already told me that they have no intention of publishing an
SPF record, and I expect they won't be any more enthusiastic about
re-writing the sender address. So, is there a way to figure out what
mail has been forwarded and exclude it from SPF testing? The email link
of Stuart Gathman's opinion seemed to imply this was possible, but
didn't explain how. Any ideas?
