Over two thirds of the email I receive that is UCE/Spam has an
"SPF_PASS" associated with it from SA. All SPF seems to do is make the
"stupid" spammers look more stupid. The clever ones aren't affected.

That would be the exact point of DK at the Postfix/ MTA level.

I would humbly submit to you that if you move that much traffic, you

technologies. If a thirty-customer/ 10k message-a-day shop like me can
implement both, I am sure that a "Big Shop" like yours can.
