('zone_id','2.35.168.192.rbl.domain.com','A','127.0.0.2')
I do this for emails, I run greylisting, and if I get >x attempts over
2 days and no emails have passed from that ip for 2weeks, they get put
on the rbl. If the reverse dns for that ip changes, or a year passes,
they are removed. It seems to work very well for me. Originally it was
designed to keep the load off the greylisting database, and is
currently running around 1.3million ip's
Quoting Curtis Maurand <[email protected]>:
so I'm assuming that my zone would be named something like rbl.mydomain.com
and then each IP address that I would block would have an ip address
of 127.0.0.2?
insert into records (domain_id, name, type, content) values
('<zone_id>', '192.168.35.2' , 'A', '127.0.0.2')
Is this correct?
Its a given that I would periodically have to purge, but I'd rather
have the system check against the localhost, then zen.spamhaus.org,
then others.

Yes, it works, why wouldn't it? RBLs just do DNS lookups and look

OT -- The only problem with having your own RBL is when will you
know to remove the listing? You will end up blocking people longer
then they should be. I've been in spamhaus before on accident,
if I emailed you during that time, I'd never be able to email you
again unless you plan on flushing out the table every few days.
Just think about the stuff like that.

Has anyone ever used PDNS to host an internal RBL. I'd like to
cut down my traffic to spamhaus before I have to start paying them
a big fee. I can harvest addresses from a mail log and put them
into a zone with an A record of 127.0.0.2.
