In order to use smtp-proxy, you must add an SMTP connector.

Important: If you are using Exchange with smtp-proxy, you must configure your server to reject invalid recipients during the SMTP session, rather than generating NDRs and sending them out later. Make sure that "Filter recipients who are not in the Directory" is checked, and Apply the settings. It's important to note here that if you have multiple Send Connectors you need to change each of these to route through SecurityGateway or the new connector you added above won't take effect.

All other systems will need to authenticate before accessing the SMTP server to prevent unauthorized users using your system to relay spam:.

This can be used if you generally want to send via DNS and only route to some systems that won't accept your email via some relay server.
