I have a very odd request.  I would like to have my own country (wouldn't we all!).    Actually, I just want SpamFilter to think that I have my own country - I want to add a custom entry into the country filter blacklist.  I want this pseudo-country to supposedly have every i.p. address on the internet, minus one, let's call it 123.123.123.123.  By blacklisting this "country" and turning on the country filter for only one of my domains, I can effectively make it so that that domain only accepts email from a single sending i.p. address, while my other domains can rely on the more conventionally used IP Blacklist.

Is this possible?  Does anyone know how to mess with the i.p. -> country mapping file, GeoIP.dat?

Thanks for putting up with my weirdness.

Stephen

To answer the headers question, only the "Received:" headers are scanned. We were seing way too many false positives by scanning all other headers...

Correct. The keyword filter just scans the email body and subject for keywords. Other filters who act on the recipient will know what the receiving domain is.

I'm not sure what you're asking...

For example the whitelist "Email FROM" filter looks at the recipient to see it's domain.
The County blacklist filter doesn't care about the recipient's domain, so it will not look at it.

Filters that look incontent, like the keywords, SURBL, and Bayesian filters, do not look at neither senders nor recipients.

Each filter acts upon something. Sometimes it's the sender's domain. Sometime it's the sender's IP. Sometime it's the recipient's email, etc.
