     My understanding is that SPF wasn't even intended to as an
anti-spam measure, but simply as an anti-spoofing measure.  However,
people starting using it that way, and the spammers were the first
ones to implement it.  This ironically meant that spam got through
and legitimate mail didn't.

     Unfortunately, the major free mail providers like outlook and
gmail require it if you're sending any kind of volume (ISP, business,
mailing list operator, etc.).  For this reason, I have setup SPF
on various systems, but I don't bother checking it on incoming
mail, as it is required, but useless.
