Hit Manual: Installing And Configuring SpamAssassin

SpamAssassin and ClamAV are a Linux mail server's best friends -- and a spammer's worst enemies. If you're comfortable working on the Linux command line and using a text editor, we'll show you how install and configure these powerful spam- and malware-killing tools.
Testing Your Configuration

You can now test your configuration by sending .exe attachments, sample SPAM and sample viruses (if you have some) to testuser. Look at the header of received emails. It should contain the following lines:

X-Security: MIME headers sanitized on server1.example.com See http://www.impsec.org/email-tools/sanitizer-intro.html for details. $Revision: 1.140 $Date: 2004-02-11 20:47:43-08
X-Virus-Scan: Scanned by TrashScan v0.08 running on server1.example.com
X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on server1.example.com
