There is a good summary why virus scanning in general has a rather high memory consumption in general. Note: especially when driven on small cloud instances, VPS or routers there were concerns about the memory consumption. For more Clamav configuration options, check the configuration files in /etc/clamav.Īdd clamav user to the amavis group and vice versa in order for Clamav to have access to scan files: sudo adduser clamav amavis A daemon is launched (clamd) and signatures are fetched every day. The default behaviour of Clamav will fit our needs. Note: Ubuntu 12.04 LTS doesn't have unzoo. Install these optional packages to enable better scanning of attached archive files: sudo apt-get install arj bzip2 cabextract cpio file gzip lha nomarch pax rar unrar unzip unzoo zip zoo Install the optional packages for better spam detection (who does not want better spam detection?): sudo apt-get install libnet-dns-perl libmail-spf-perl pyzor razor To begin, install (see InstallingSoftware) the following packages: sudo apt-get install amavisd-new spamassassin clamav-daemon If this is not the case, follow the Postfix guide. You should have a functional Postfix server installed. This is a classical installation of Postfix + Amavis-new + Spamassassin + Clamav. In this howto, integration with Spamassassin and Clamav will be presented. Amavis-new is a wrapper that can call any number of content filtering programs for spam detection, antivirus, etc. In this howto, Postfix integration with amavis-new will be presented.
