Sendmail filter that rejects spam and viruses from zombie PCs
'smf-zombie' is a Sendmail filter that rejects spam and viruses from zombie PCs. It blocks up to 95% of the mail sent by spam/virus engines, checks the sender's IP address with a reliable RBL (cbl.abuseat.org), safely rejects "alien" bounces without violating any RFC, rejects messages for undisclosed recipients, and rejects harmful attachments to keep viruses from spreading. It is lightweight, reliable, and simple without a myriad of options.
