Introduction

Clam AntiVirus (ClamAV) is a free, cross-platform antivirus software tool-kit capable of detecting many types of malicious software, including viruses. One of its main uses is on mail servers as a server-side email virus scanner. The application was developed for Unix and has third party versions available for AIX, BSD, HP-UX, Linux, Mac OS X, OpenVMS, OSF and Solaris.

Administration

1. Find out whether the MTA is complaining about ClamAV:

   
   % sudo tail -f /var/log/maillog
   
   

2. If necessary, restart the ClamAV milter:

   % sudo /usr/local/etc/rc.d/clamav-milter stop
   % sudo /usr/local/etc/rc.d/clamav-milter start
