FWIW, Ive read some stuff on the anti-spam groups claiming that some of the spamware intentionally targets backup MXs, since they tend to have less robust filtering. >From what Ive seen, I think this is the case. Awhile ago we went to doing our own secondary MX protected with another Gnatbox located at a remote office. Ive got some scripts that grep out the RBL entries from the Gnatbox logs and mails them to me. The *vast* majority of connects to the seconday MX get blocked by the RBL. For example, from yesterday it looks like something around 3% of the connect attempts to that Gnatbox were legit. The other 97% were blocked by ORDB. > While doing some looking on orbz site I found that I could sign up to run > local copies of their database.

I mean it should resolve to my local copy instead of going > across the Internet shouldn't it? It should. That server should think its authoritative for the inputs.orbz.org domain. You should be able to manually test it by trying to resolve 7.33.94.210.inputs.orbz.org for a mail server IP of 210.94.33.7. BTW, we're using ORDB in front of input.orbz.org, and it looks like there is darn near nothing that orbz catches that ORDB doesnt. The ORDB database has something like 120000 addresses compared to 70000 in orbz, and I like the ORDB interface quite a bit better.
