Virus Protection - Unix Specific Instructions.

For unix we recommend CLAMAV as the primary scanner, it's easy to install on most unix systems and gives a good broad protection.

The settings below are an example, the auto configure button in the web admin virus page should configure surgemail correctly but you must manually install CLAMAV yourself first (See below)

You may also wish to use our cloud based scanner to enhance clamav scanning.  g_virus_cloud "true", note that this setting sends samples of attachments from your server to our cloud server for analysis, the samples are never stored/kept after scanning.  Only a subset of suspect high risk messages are scanned this way.

CLAMAV Settings.

These will be set in surgemail.ini by the auto config button: (path to clamdscan may vary)
    g_virus_cmd "/usr/local/bin/clamdscan --stdout --no-summary --remove $FILE$"
    g_virus_cmd_codes "1"
    g_virus_strangers "true"

CLAMAV Installation

On most modern systems you can install clamav by typing:
    sudo apt-get -install clamav

That should be all you need to do, then use the auto configure inside surgemail's virus page to set surgemails settings and test it.

If that doesn't work check this page for Operating System Specific packages for most versions of linux, or if all else fails you can follow the build from source instructions:
