An auto response definition is used with an auto response policy to automatically issue a response for inbound emails to Mimecast from external senders. Administrators can configure the text or HTML to be used, as well as the other variables for the notification.

This feature is only available for customers that use the latest email Gateway.



To create or change a definition you must:

  • Be logged on to the Mimecast Administration Console.
  • Have access to the relevant Gateway menu item for the definition being created or changed.
