I'd say that SPAM filtering causes more lost mail: silently discarded, placed
in the SPAM folder never to be seen again, than trouble with SPF. The
difference being the results of an SPF check failure is returned to you and is
thus visible, false positives 'magically' disappear - no problem at all there
then ;-)
