I'm not sure what you're saying. You think the spammers are no longer
using your domain as the source of their mail? I find that unlikely.
To me, SPF is not about stopping spam,
it's about stopping spam that purports to come from my domain(s).
But SPF doesn't achieve that, because it still allows:
MAIL FROM:<SRS0=xx=yy=kitterman(_dot_)com=spf2(_at_)forwarder(_dot_)org>
From: Scott Kitterman <spf2(_at_)kitterman(_dot_)com>
99.5% of recipients really won't be able to tell the difference.
