I subscribe to ip2location.com, which provides geolocation services by IP address. The info is downloaded on nightly from their web servers and put into a database. I check the IP addresses contained in the message against the database and if it's from a foreign country, I block it.
You can allow some foreign countries through if you choose... it just takes a little coding. -- Dave -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Philip Prindeville Sent: Friday, January 27, 2006 7:46 PM To: [email protected] Subject: Re: [Mimedefang] Adding support for learning our addresses David F.

I was hoping to be able to blacklist certain countries, etc. like Romania, China, Thailand, etc. that aren't identifiable by rDNS. I suppose a way to manually reset a blacklisting could be done. Or do apply it per a criteria. BTW: my SpamAssassin pukes at "use_terse_report 1". What version does that apply to? -Philip _______________________________________________ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.
