Reference snapshot:

Yes, its Running in MTA Mode.

If we receive an external Mail, we want it to be tagged as [external].

The Reason is, sometimes we are getting Spam Mails where People trying to fake like its coming from an Internal Address. So its really easy and clear to see which E-Mail is coming from External or Internal
