Use the EAC to Create a Receive Connector to Receive Messages from the Internet

1. In the EAC, navigate to Mail flow > Receive connectors. Click Add to create a Receive connector.

2. On the New receive connector page, specify a name for the Receive connector and then select Frontend transport for the Role. Since you're receiving mail from the Internet in this case, we recommend that you initially route mail to your Front End server or servers, to simplify and consolidate your mail flow.

3. Choose Internet for the type. The Receive connector will receive mail from Internet senders.

4. For the Network adapter bindings, observe that All available IPV4 is listed in the IP addresses list and the Port is 25. (Simple Mail Transfer Protocol (SMTP) uses port 25.) This configuration indicates that the connector listens for connections on all IP addresses assigned to network adapters on the local server.

   Note

   If you have multiple network adapters, you can add an IP address that is assigned to a specific network adapter on the local server. But this configuration isn't required.

5. Click the Finish button to create your connector.

Once you have created the Receive connector, it appears in the Receive connector list. If you would like to see an example of how to create a Receive connector with a cmdlet, see New-ReceiveConnector.

How do you know you've successfully created a Receive connector to receive messages from the Internet?

To verify that you've successfully created a Receive connector to receive messages from the Internet, send mail from an outside source and verify that one of your users can receive it. If you can receive mail, you know that the configuration worked successfully.
