How to Configure a Relay Connector in Exchange Server 2013

A very common scenario for Exchange Server 2013 administrators is the need to allow applications and devices on the network to use the Exchange server as an SMTP service.

• External SMTP relay – the ability to make an SMTP connection to an Exchange 2013 server and send email to recipients that are outside the organization (for example, applications or hardware that sends automated reports or alerts to external vendors or consultants)
