Can we skip the discission re how effective SPF is,
it's flaws (perceived or otherwise) and how widely
(or not), it's been adopted?
As the person dealing with the blowback due to the
forgery I mentioned, there was little difference to
me whether it was bounces or sv - all of it was
unwanted.
And that's all I say about the matter, in deference
to the moderators.
