Virus scanning of email and files

NetManager includes the ClamAV antivirus engine for detecting trojans, viruses, malware & other malicious threats. It can be enabled by adding the following to the settings file and running the antivirus build script:

antivirus_enable="y"

When enabled, new virus definitions are checked for every 2 hours.

To enable scanning of incoming mail, add the following to /etc/mail/wordconf:

antivirus=yes

You can check mails are being filtered by looking at the mail headers. You should see a line like the following:

X-NetManager-AntiVirus: ClamAV 0.98.7/21125/Wed Dec  2 13:36:35 2015

Scanning users' home areas

The avscan command can be used to scan users' home areas (either a list of users can be given or all users can be scanned). It can be set to email the results either to the owner of the home area or to a given administrator address.

Syntax: avscan [-avu] [-n nice] [-e email] <username> [<username> ...]
        -a = scan all users
        -v = verbose progress
        -u = email each user with information about their home area/email
        -e = email summary to given address, otherwise send to stdout
        -n = set priority level with nice to given level (default +10)
