Re: Reputation based filtering...

Check out RepuScore: http:.//isr.uncc.edu/RepuScore. The spamassassin plugin we designed computes reputation and stores them in a database. We have not closed the 'loop' using reputation to classify emails, yet. But, you can use it as a part of spamassassin scoring. --- Gautam Singaraju

Does anyone know of a list of whitelisted domains?

I have to identify a list of 25 million domains as whitelisted/blacklisted at some point of time. Does anyone know such lists which maintain historical info? --- Gautam
