Send connectors are used to send emails out from your Exchange organization to the Internet. When you install Exchange 2016, receive connector is configured by default but there is no send connector configured by default. To be able to send emails out on the Internet you need to configure send connector in Exchange 2016.
Configure Send Connector in Exchange 2016
There are different types of send connectors in Exchange 2016. They are: –
- Custom: – Allows you to send emails to other non-Exchange mail servers.
- Internal: – Choose this option if you have Edge transport server and you want to route emails via Edge transport server.
- Internet: – This send connector is used to send email out on the Internet. Choose this option if you are configuring send connector in order to send emails on the Internet.
- Partner: – This send connector is used to send emails to third party servers using TLS encryption and certificate authentication.
To configure send connector to send emails out on the Internet, log on to Exchange Admin Center (EAC). Click mail flow on the features pane. Select send connectors tab.
Click Add + “New” to add new send connector.
Type name of send connector. I typed MBG Send Connector. Name is just to recognize the send connector. Choose Internet to send emails out on the Internet. Click next.
There are two methods to send emails on the Internet. You can send emails using smart hosts or use DNS server. Smart hosts can be SMTP server of your Internet service provider or any other SMTP provider. Here, I will select MX record associated with recipient domain which uses DNS lookups to find recipient’s mail server. Make sure your internal DNS server can resolve external domain names. Click next.
Under address space click + “Add”. You can use separate send connectors to send emails based on address space. You can use one send connector to send emails for xyz.com domain and use different send connector to send email to abc.com domain.
If you want this send connector to send emails to all domains then type * under FQDN. Click save.
Review the configuration. Click next.
Click + “Add” to choose your Exchange server. Select the Mailbox server from the list and click add. Click OK.
Review the configuration. Click finish.
Send connector has now been configured as shown above. Now, you should be able to send emails out on the Internet.
