All,
We use milter-greylist 4.4.3. We plan to upgrade later this
summer. I want to evaluate a few DNSRBLs that are cached locally. I am
interested in understanding which lists have more bang for their buck. It
would be benneficial to write a meta DNSRBL rule that was positive if it
was on both lists and then if not to continue list evaluation. Has anyone
ever done anything like this?
Thanks,
Jonathan
