Mailscanner is an e-mail security and anti-spam solution for e-mail gateways. In combination of postfix it uses a very ugly way messing around in postfixs queue directories. Anyways .. if you are still interested, keep reading.

Mailscanner was removed from Debian, so it’s not available in wheezy. Anyways … there is a web 2.0 Frontend for Mailscanner, called Baruwa, which provides mailscanner packages for Debian.

Add the baruwa sources file

cat > /etc/apt/sources.list.d/mailscanner.list << 'EOF'
deb http://apt.baruwa.org/debian wheezy main
deb-src http://apt.baruwa.org/debian wheezy main
EOF

Optional, install the GPG key for the reprosority

wget -O - http://apt.baruwa.org/baruwa-apt-keys.gpg | apt-key add -

If you’re running squeeze with Mailscanner, you should do this before upgrading to wheezy. If you are installing Mailscanner on a fresh wheezy, just:

aptitude update && aptitude install mailscanner

As of Version 4.78 and above, you can place you local changes into /etc/MailScanner/conf.d/, no need to mess directly around into /etc/MailScanner/MailScanner.conf
