No. You can set up your own rbldnsd, but that's about as close as
you get.
Most of us who have an explicit IP or IP range we want to block either
use our firewalls, or our MTA access controls to deny the message
before
it ever gets delivered. This saves us considerable bandwidth and
processing time.
Bummer. That works with absolute blocking, like with narrow
professional spammer ranges, but not so well with IP based suspect
ISP, country or regional scoring for mixed spam/ham. I'll keep looking.
Thanks again,
