SPF can help a bit, if the receiver of the spoofed emails uses SPF for
filtering and does not bounce on SPF violation.
We've been able to limit the bounces that get through so far to just a few,
mostly through detection of any remnants of the original spam in the bounce.

be that many, but every little bit helps.
