Thanks for confirming that spf doesn't fix the problem.
The main problem with SPF is that most other servers out there don't
check it even if you set your own records correctly.
The question was whether spammers avoid joe jobbing addresses in domains
that have SPF set (except with a +all). it seems some of them do and
some don't.
I've been joe-jobbed since I implemented SPF and maybe it's possible I
would have gotten more backscatter without it, but I still got plenty
because the servers which got the email in the first place didn't
check SPF to see that it wasn't coming from me. The sadly funny time
was when I got backscatter from a server with an accompanying message
of "this email failed SPF so it probably didn't come from you, but
just to be safe I'm returning it to you anyway" - great, thanks.
DKIM would have the same issue - doesn't mean anything if the other
folks don't check it.
