The antivirus system scans mail messages as they pass through your mail server.
If you did not select this module to be included during the installation process, you must first install the module.
You can find this feature in the menu system at the following location:
The open source ClamAV solution is the antimalware engine used in ClearOS Enterprise. This software automatically checks for updates several times a day for new antimalware signatures. This is already included in ClearOS Enterprise for free!
In addition, the ClearSDN Antimalware Updates service provides additional daily signature updates to improve the effectiveness of the antimalware system. These signatures are compiled from third party organizations as well as internal engineering resources from ClearCenter. We keep tabs on the latest available updates and fine tune the system so you can focus on more important things.
When configuring the antivirus system, you must make some mail policy decisions. There are three types of policies available:
When a virus is detected, you can choose to either discard the message, or pass the message through. We recommend discard mode for most installations.
The antivirus software not only performs virus scanning, but also manages file attachment policies. Certain types of file attachments are prone to viruses. The ability to block attachments by file extension is another layer of security for your mail system.
Select the file extensions that you wish to ban from going through your mail system. Both internal and external mail are checked.
<note warning>Some Microsoft Office documents contain embedded binary files (.bin). If you need to allow Microsoft Office documents through your mail system, please do not ban the .bin file extension!</note> search?q=clearos%2C%20clearos%20content%2C%20userguide%2C%20Mail%20Antimalware%2C%20app-mail_antimalware%2C%20clearos5%2C%20categoryserver%2C%20subcategorymailscanning%2C%20maintainer_dloper&btnI=lucky
