Actually, "SPF" has been going out of vogue for awhile now and sensible
mail admins do not make accept/deny decisions entirely on pass/fail of
SPF tests. Many SAs are finding it causes more problems than it solves.
When added to the fact that its use is by no means universal, its
continued use is seriously in doubt. In other words, "Use at your own
risk." There are, as has been pointed out, better methods available.
