Not to start a polemic and a huge thread (we all have better things to
do, right?), but SPF is a broken concept that doesn't work with
forwarders. DKIM does work always and is much much better.

The only thing we do is:

if ( SPF_check_failed_or_none )
	use_grey_listing

I think this is the only way to make it acceptable.
