SPAM FILTER

I am looking for a web-based spam filtering program/service. The program should run on Windows 2000 server, preferably written in VB 7 (dot net). I would like to be able pass this program a string (the body of the email message along with all headers) and get an integer value (0-10) back. The return value determines the likely hood of the email message being a spam. The higher the number, the more likely the message is a spam. I have been able to find spam filtering source code on the net but most of them are pearl based. I need this to work on Windows 2000 server. Some of the sources are [[login to view URL]][1] , [login to view URL] The program should allow the user to add email-filtering criteria to consider any given message a ‘spam’. For example add filleting keywords, email addresses, domain names etc to black list a message. The program should also do a DNS lookup based filtering (some technical info available at [login to view URL]). ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Exclusive and complete copyrights to all work purchased. (No GPL, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site). ## Platform O/S: Windows 2000 server Suggested develp language: VB .NET
