Hello Idris,

If you have sophos central managed endpoints then you use the following KB article to install message relay and update cache and then use the command like interface to specify the location of message relay when running the installer.

You can get all the command line installation parameter from below KB article

Now all you need to do is run the sophos installer through windows command prompt with the following command

Install using a Message Relay:

SophosSetup.exe --messagerelays=192.168.10.100:8190 ( Note: Use the Ip address of the server where you have message relay and server should be able to reach to internet)

Let us know if you need further assistance on it
