You would be less of a troll if your article was on "why not SPF
when you, as a receiver, are using forwarders".  It should be turned
off only for your non-SRS forwarders.  It should not be turned off
in general unless you have no clue who your forwarders are, or are
a big mail provider whose customers have in general forgotten what forwarders
they have set up.

Actually, my software *uses* SPF even for non-SRS forwarders.  If
the connect IP matches the forwarder domain SPF record, it bypasses
check SPF on the actual MFROM.  That way, I don't have to track
specific IP addresses that the forwarder uses.
