Ummm.... are you really that unclear on the concept? I'll explain it
carefully:
Spammers know that (some) filters filter less aggressively than normal
on an SPF "pass". So they register a throwaway domain and use that
in the envelope sender. They publish a TXT record for that domain to
ensure they get an SPF pass.
There. That wasn't so hard, was it?

and how does that care a SA setup?
SA setup will detect such domains and will score mail positively.
Is there something other to explain?
