    4. Once the antivirus core scanner is installed, you can then proceed with the MailMonitor install.
    5. Install Neverfail Heartbeat for Exchange.

  • Due to the monthly software release cycle of Sophos, Neverfail recommends that:
    1. Prior to installation of Neverfail Heartbeat on a server running Sophos Anti-Virus, the version information is checked against the AMX module name.
    2. Installs can only be performed against certain versions of the Sophos software, however it is possible to upgrade to the latest version of the Sophos software after installing the AMX, please contact support if your version does not match the AMX.
  • Further Sophos specific information is contained in Knowledgebase article #141 - Apply Exceptions After a Switch When Using Sophos MailMonitor for Exchange'.
  • If you are only using the File Level component, and do not have the MailMonitor for Exchange component installed, then you do not require the AMX. Microsoft Exchange and Microsoft SQL Server directories must be excluded from File Level AV scans as advised by Microsoft and Sophos.
