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. The link for this article located at Linux.com is no longer available. .

POPULAR OPEN SOURCE virus scanner Clamav has been hastily updated this morning to remove a 'false positive': the scanner was detecting the GNU Public Licence as a virus. Thousands of Open Source programs, including Clamav itself, include a copy of this licence, and since it is a plain text file it is incapable of containing a virus. The incident may well bring a smirk to the lips of those who object to the GPL on ideological grounds. The cry is often heard that the GPL is 'viral', since you can't redistribute GPL code with proprietary code without the result being 'infected' with the GPL. At least not if the result is a 'derivative work' of the GPL code. What exactly constitutes a derivative work is something we'll leave to the lawyer-geeks of places like groklaw.net.

It can also detect a large proportion of unsolicited commercial e-mail (spam) passing through it. Not only can it scan for known viruses, but it can also protect against unknown viruses hidden inside e-mail attachments by refusing entry to attachments whose filenames match any given pattern. This can include generic patterns that trap filenames attempting to hide the true filename extension (e.g. ".txt.vbs"). Attachments containing viruses that can be disinfected (e.g. word processor macro viruses) are automatically disinfected and sent on to their original destination. It is superior to many commercial packages in its ability to handle Denial Of Service attacks caused by messages containing files such as the "Zip of Death". It is easy to install into an existing e-mail gateway, requiring very little knowledge of sendmail and no change to an existing sendmail configuration.
