On a bit more sophisticated level (ok a lot more sophisticated level), a guy
named A.J. Fasano has developed a fantastic system that has one part of it
that does the type of lookups you are referring to. He calls it
relayregistry.org and it's fantastic. One of the things he focuses very
well on doing is helping ham get through which is something I think is often
forgotten in the anti-spam world.
If you would like to use the system, email me your daily mail volume and
I'll forward your request. If approved, I'll send you the MD code and SA
rule files.
BTW, anyone out there doing any REALLY scary mail volumes like 100Million+
daily emails? Really like to discuss if SA and MD can handle this type of
volume and what type of hardware requirements, etc.
Sincerely,
KAM
One other thing I thought about: what about detecting spammers, and
then looking up the CIDR block that their address belongs to, and adding
it to a blacklist automatically in filter_relay()? We could set a
threshold for the number of offenses before they get added in.
