I have nothing but the utmost respect for the Spamhaus project. What is Spamhaus? For those who don’t know I wll reproduce the quote from its web site: “Spamhaus tracks the Internet’s Spammers, Spam Gangs and Spam Services, provides dependable realtime anti-spam protection for Internet networks, and works with Law Enforcement to identify and pursue spammers worldwide.”
And this is not boasting but 100% true. You just need to add a line to your E-mail server like Sendmail or Postfix and you are all set! Spamhaus filter catches up to 70% of all junk and spam e-mails. In fact, there are several filters that you can set up with Spamhaus.
I heard some sysadmins comlaining that sometimes spamhaus jamms a couple of legimitate addresses. Yet, nothing happens without reason. Somehow these “legimitate addresses” got busted somewhere in most cases and were included in Spamhaus blacklists. If one believes that such thing occured, he needs to go and resolve this issue with Spamhaus, not with you.
So, if you are interested in clearing your cluttered shiny new E-mail server from spam and junk, visit the Spamhaus project.
