In Microsoft Exchange Server 2013, a Send connector controls the flow of outbound messages to the receiving server. They are configured on Mailbox servers running the Transport service. Most commonly, you configure a Send connector to send
outbound email messages to a smart host or directly to their recipient, using DNS.

, and from the left side pane, click on Mail Flow
and then click on send connectors
- Under send connectors, click the Add button
to create a new send connector
- The new send connector wizard will open, where you have to give it a name and choose a
Type appropriate to your connection scenario. The type determines the default permission sets that are assigned on the connector and grants those permissions to trusted security principals. Security principals include users, computers, and

Type, select Internet . Then click next
