           My Life with Spam [Mark-Jason Dominus] 
      
 -  I get a lot of spam mail, and I don't like that. I used to get upset every time I read my mail and had to throw out a                bunch of spam, so I decided to put some effort into writing a program that would filter my email and discard spam                automatically. Then my blood pressure would stay low.

           Qmail RBL  
      
 -  Paul Vixie is involved in a project called the Mail Abuse Protection System (MAPS). He is publishing his list of sites which
 engage in, or tolerate abuse of email. This Real-time Blocking List (RBL) is available, well, in real-time. This list is
 available as a BGP feed, or through the DNS. Dan Bernstein has a fake SMTP server called rblsmtpd which consults the
 RBL and traps accesses by RBL'ed hosts.
