RBLcheck
RBLcheck is a program that assists against the annoyance of spam email.
It can be used to check email messages whether they were sent though well-known open mail relays, or other frequently used hosts on the Internet.
It does so by checking the hops the email message went against some real-time blacklists. If found, it tags the message with the score. What you want to do with the message, is up to you; you can build filters to check the tags added by RBLcheck, and act upon them.
