Despite the ostentatious claims made by its originator ("Spam as a
technical problem is solved by SPF"), SPF has no anti-spam value.
Nor should it be used when deciding whether to generate a bounce:
the answer to that is always "no". It's far better to reject (not
to mention far simpler, with any sane MTA) and thus greatly diminish
the possibility of outscatter/backscatter spam.
