Add Anti-Virus support to MailScanner

To make sure that MailScanner
scans on virus you can add several different anti-virus systems. The
way I have configured it is to make use of Clamav. You can also use
multiple virus scanners with MailScanner.

You need to have an or multiple virus scanner(s) installed on your
system that MailScanner can use. Here we show an example on a Debian
system with Clamav:

Installing and Configuring Clamav

• If you want to make use of the Clamav on a Debian system you need to add the volatile source to sources.list

echo "deb http://volatile.debian.net/debian-volatile etch/volatile main contrib non-free" >> /etc/apt/sources.list
apt-get update

• To install Clamav:

apt-get install clamav clama-daemon clamav-freshclam unrar

• During the installation you should get a message to select your update source for clamav just select the nearest to you.

Configuring MailScanner

• Open the configuration file ( /etc/MailScanner/MailScanner.conf )
  for MailScanner with you favorite editor. You can change this options
  to the installed virus-scanners

Virus Scanners = clamav

• Or you can use the default configuration, I prefer the default
  configuration so when you decide to install an additional virus scanner
  you don’t need to adjust MailScanner

Virus Scanners = auto

• Now restart MailScanner

/etc/init.d/mailscanner restart

• Check MailScanner

check_mailscanner

• If the output of check_mailscanner is the same as below here, MailScanner has started successfully

dionysus:~# check_mailscanner
MailScanner running with pid 7589 7590
