The PTR is mandatory.  The vast majority of SMTP senders without proper
PTR records are zombie machines spreading spam.  Anyone running a real
mail system should be capable of arranging for a correct PTR in the DNS
-- if they aren't then they have no business at the controls of a MTA.

As far as I know, the FreeBSD.org mailers don't pay much attention to
SPF -- generally the accepted practice seems to be to use SPF as part of
computing Spam scores, but not to make accept/reject decisions solely
based on SPF.

	Cheers,
