Add a New Mail Server and Domain

You can set up Message Security to protect multiple mail servers.

These instructions are a minimal set of steps needed to establish mail flow, and assume that you are adding a new Email Config organization under your Account org. Consider enabling other features for the new server, such as Connection manager, Spool Manager, Alerts, and TLS.

To add a new email server and domain to your service:

1. Go to the Orgs & Users > Orgs page and select your Account organization.
2. Select “Create Email Config” in the Orgs & Users > Orgs page. On the Org Settings page, under New Org, enter a name for your Email Config, usually “Email Config for [Domain],” then click Add.
3. Enter delivery information for your mail server by entering your mail server’s domain name or IP address in the Delivery Manager > Edit page. See Setting up Delivery Manager for more information.
4. Add a sub-organization to the new email config. See Create an Organization for more information.
5. Add domains and users to this sub-organization. See Add a Domain for Filtering and Add / Delete / Move Users for more information.
6. Change DNS MX entries to route your mail traffic to the email protection service for a domain. See Edit a Domain for more information.

For more information, see Creating an Email Config in the Email Security Service Administration Guide.
