Insert an X-Header

The Insert X-Header action adds an X-Header to the message header before sending a message to the intended recipients. An X-Header consists of a name field and a body field, which can be customized according to your requirements.

Insert X-Header is one of the "Modify" class of actions.

  1. Select Insert X-Header from the Modify section.
  2. Type the X-Header name and body.
    Note:

    Do not use or start your X-Header name (case-insensitive) with the following since they are reserved for Trend Micro Email Security:

    • X-TM

    • X-MT

    The reserved X-Headers might be adjusted dynamically if necessary.
