Linux provides several server-based anti-virus applications, most of which can be configured to interact with a variety of messaging servers. Many use the actively developed ClamAV open source virus toolkit on the back end; others work with proprietary or commercial scanners. In this article we'll compare MailScanner and Anomy Sanitizer on a Sendmail messaging server. Scanning emails for viruses even before it reaches the user's desktop is a very important step in protecting your users and the network as a whole. This article talks about two email virus spanners, MailScanner and Anomy. Do you have any other favorites?

Before you install an anti-virus scanner on your server, you should install ClamAV. You can get it up and running from scratch in about 10 minutes. Most Linux distributions' clamd.conf files are already configured to scan mail. Also, quite conveniently, most distros' ClamAV configurations are set to check for virus signature updates several times a day. ClamAV even has several SMTP scanners for sysadmins who want to make sure their users aren't sending anything infected.
