SpamNinja - catching the big players silently

In the past I often got spammails from addresses like Mitgliederservice <> that slid through SpamAssassin. That mails differ from regular spam quite a lot.

  • The mails are DKIM-Signed and pass the SPF check
  • They are correctly formatted (ISO-8859-1)
  • They are written in correct german

On an antispam board I found out that this seems to be a professional spammer: Aquatix. As there is nobody (except RIPE) to complain to, I created SpamNinja.

This tool takes a list of RIPE owner-handles and blocks all networks that are assigned to that owner. I don't expect any valuable traffic from that networks as all that ranges belong directly to a professional spammer.
