To route mail to ArcTitan from G Suite, first you must set up a Host Route.


In your G Suite console, go to Apps > G Suite > Gmail > Advanced Settings > Hosts, and add a new Host, pointing to your ArcTitan server on port 25:

Once that is created, you will need to create a Route, under Apps > G Suite > Gmail > Advanced Settings > General Settings, adding the X-Gm-Original-To header.

In addition to that, you must add a recipient to use that Host Route that we added earlier, and setting it to company_tag@arctitan-eu1.titanhq.com (or whichever server you are on):






After that, make sure to save your settings. Mail coming into your organization will now start getting sent to ArcTitan as well, and will be searchable shortly after.
