ASSP stands for Anti-Spam SMTP Proxy. The ASSP server project is an Open Source platform-independent transparent SMTP proxy server that leverages numerous methodologies and technologies to both rigidly and adaptively identify spam.

How to Build an Effective Mail Server Defense

tends to limit the issue to message applied security measures, and even

Virtual Users And Domains With Postfix, Courier And MySQL (Fedora Core 5)
This document describes how to install a mail server based on Postfix that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.

Security Testing your Apache Configuration with Nikto
By now you've got the perfect setup for your new Ubuntu 6.0.6 (Dapper Drake) box. You may have even followed the excellent Intrusion Detection and Prevention with BASE and Snort tutorial. And as an added precaution you installed DenyHosts to prevent hack attempts via ssh. But now that you've got your new LAMP server on the internet, how can you tell that your new web server is secure? You test it, of course!
Postfix Spam Filter using Ubuntu Dapper, MailScanner, SpamAssassin, Rayzor, Pyzor, DCC and ClamAV
This is a similar version of the HOWTO that can be found here: http://www200.pair.com/mecham/spam/spamfilter20050628.html.
Except for using Ubuntu Server instead of Debian and MailScanner
instead of Amavisd, the Postfix, Rayzor, Pyzor, DCC and ClamAV sections
are almost the same.
Intrusion Detection With BASE And Snort
This tutorial shows how to install and configure BASE (Basic Analysis and Security Engine) and the Snort intrusion detection system (IDS) on a Debian Sarge system.
