(I removed our domain on the screenshot)


Is this possible on the Sophos Email Appliance and how can I do this ?

  • I opened a support ticket and got this reactions:

    "We are aware of the need to disable this (Logged with Development under SEA-290) but we do not yet have a version where this will be resolved."

    "The current expectation is that this will be addressed Q2 2019"


    To be continued....... ;)
