I don't understand why this mail would be rejected. Unless it's just
rejected due to the normal brokenness of SPF when mail is forwarded?

i think we can rejigger SRS to not rewrite if SES is seen.

It would be better to have SRS happen _only_ if the original source
address has IP-dependent mechanisms followed by '-all', and preferably
also only if the recipient is known to check SPF.
