I've got barrac, zen, spamcop in postscreen, and still getting lots of spam

then catching a lot with dbl.spamhaus (dbl both as postfix rhs block and as BIND DNS blackhole (dbl = postfix sender domain not found), while BIND with DBL/RPZ also blocks our recursive clients from accessing DBL domains.

after harvesting 90 days of legit sender domains to whitelist from rate limiting, postfwd's rate limiting is catching 1000s of spam that get through the above.

Weirdly most of the rate-limited sender and PTR/reverse domains are later found in dbl, so I think the rate-limiting catches them before they are in dbl.

what gets through mx1/postfix to be blocked by old barracuda 600s I inherited (and will soon will turn off) is about 0.5%, crumbs, of our blocked total.
