Filtering PDF-/XLS-/Image-Spam With ClamAV (And ISPConfig) On Debian/Ubuntu

Post date: July 24, 2007, 02:07 Category: Security Views: 3315 Comments
Tutorial quote: There is currently a lot of spam where the spam information is attached as .pdf or .xls files, sometime also hidden inside a .zip file. While these spam mails are not easy to catch with e.g. SpamAssassin or a Bayes filter, the ClamAV virus scanner can catch them easily when it is fed with the correct signatures as ClamAV is built to scan mail attachments.

Fight Image Spam With FuzzyOCR And SpamAssassin On Debian/Ubuntu

Post date: February 15, 2007, 18:02 Category: Software Views: 3217 Comments
Tutorial quote: This tutorial describes how to scan emails for image spam with FuzzyOCR. FuzzyOCR is a plugin for SpamAssassin which is aimed at unsolicited bulk mail containing images as the main content carrier. Using different methods, it analyzes the content and properties of images to distinguish between normal mails (ham) and spam mails. FuzzyOCR tries to keep the system load low by scanning only mails that have not already been categorized as spam by SpamAssassin, thus avoiding unnecessary work.

SpamAssassin, ClamAV and Procmail Howto

Post date: April 16, 2005, 00:04 Category: Network Views: 2990 Comments
Tutorial quote: This document describes how to install SpamAssassin (for filtering SPAM) and ClamAV (for filtering viruses, trojans, worms, etc.) and how to invoke them by using procmail recipes. It is suitable for scenarios where Sendmail or Postfix deliver emails to local users. It should work (maybe with slight changes concerning paths etc.) on all *nix operating systems. I tested it on Debian Woody so far.

In the end you will have a system where Sendmail or Postfix deliver emails to a local user; the emails are passed to procmail which invokes SpamAssassin and ClamAV in order to filter the emails before they arrive in the user's inbox. However, the installation of Sendmail and Postfix are not covered in this document.

This howto is meant as a practical guide.
