Part 1: Add mail server for Gmail email routing
Before you create a routing setting you must add the details of your legacy server (the third-party provider) to the Admin console. This is done by adding a new host (also known as a route).
Step 1
If you are not already signed in, sign in to your domain as the Administrator at admin.google.com.
Step 2
From the main menu, navigate to Apps, select Google Workspace, and click Gmail.
Step 3
Click Hosts.
Step 4
Click ADD ROUTE.
Step 5
Enter Legacy Mail Platform in the Name field.
This is where you enter the legacy mail server details. You must specify a public hostname or IP address. For more complex environments, you can also add a primary and secondary configuration, each of which can consist of multiple mail servers. To keep things simple, let's assume you only have one mail server.
Step 6
In the Specify email server section, enter the hostname my.legacyserver.com. (This is just a test name and doesn't actually exist).
Step 7
For the purposes of this exercise, enter 25 as the port number.
Step 8
