mod_defensible is an Apache 2.x module intended to block spammers/hackers/script kiddies using DNSBL servers. It will look at the client IP and check it in one or several DNSBL servers and return a 403 Forbidden page to the client. This guide shows how to install and use it with Apache 2 on a Debian Etch server.
HOWTO Spam Filtering with Spamdyke in front of Qmail - Gentoo Linux Wiki
(via)This HOWTO should give an overview on using spamdyke SMTP filter in front of the mail-mta/netqmail mailserver. From the spamdyke website:
spamdyke is a filter for monitoring and intercepting SMTP connections between a remote host and a qmail server. When a connection is established from a spam source (as determined by the active filters), spamdyke will reject the email -- qmail never sees it.

Full Mail Server Solution w/ Virtual Domains & Users (Debian Etch, Postfix, Mysql, Dovecot, DSpam, ClamAV, Postgrey, RBL) | HowtoForge - Linux Howtos and Tutorials
This guide describes how to set up a full email solution in Debian Linux (all code is from Debian Etch). I was asked to design a secure, scalable, portable solution for a small company. While the guide references many 'servers', the company only had 4 physical machines, Xen was used to virtualize the entire solution. That particular aspect of the system is not discussed in this guide, although I will try to get it into the next revision.
Nuclear Elephant: The DSPAM Project
DSPAM is a scalable and open-source content-based spam filter designed for multi-user enterprise systems. On a properly configured system, many users experience results between 99.5% - 99.95%, or one error for every 200 to 2000 messages. DSPAM supports many different MTAs and can also be deployed as a stand-alone SMTP appliance. For developers, the DSPAM core engine (libdspam) can be easily incorporated directly into applications for drop-in filtering (GPL applies; commercial licenses are also available).
