PoliteMail Server, whether internally installed or cloud-hosted, may be connected to deliver email direct to your Exchange Server. This is ideal for internal employee communications, as well as for keeping all email delivery within your existing email infrastructure.
PoliteMail enables hands-off Exchange integration, and email is delivered to Exchange via an SMTP Smarthost connection (sometimes thought of as a mail relay).
The best way to accomplish this is to utilize the Exchange Management Console Edge Transport or Hub Transport Service and add a Receive Connector which may be isolated to a specific IP address and authenticated.
Please contact your Account Representative if you need documentation on how to set up a receive connector.
