smf-zombie is a SendmailTM filter for SPAM and virus filtration from zombie PC.
More than 80% of SPAM is going from the infected Windows computers (zombie PC).

This filter aims to be lightweight, reliable, and simple rather than have a myriad of options. It's written in C and works under Linux/BSD/Solaris.

Here are some key features of "smf zombie":
It only scans the messages less than defined size;
It has a hosts/networks whitelist;
It blocks most of the SPAM/virus engines (up to the 95% of them);
It checks sender IP with most reliable RBL - cbl.abuseat.org;
It safely rejects "alien" bounces without RFC violating;
It rejects messages for undisclosed recipients;
It rejects harmful attachments to prevent virus spreading;
It logs all filter activities to syslog.
Small code (does not exceed 400 lines);
Fast work;
Stability (production quality);
Low resources are required;
No temporary files are created.
