Configure SMTP servers


You can configure the API Gateway to use a specified Simple Mail Transfer Protocol (SMTP) server to relay messages to an email recipient. You can configure the SMTP server as a global configuration item under the Environment Configuration > External Connections node. The SMTP server is then available for selection in the SMTP filter in the Routing category.

To configure an SMTP server, right-click the Environment Configuration > External Connections > SMTP Servers node, and select Add an SMTP Server. Alternatively, in the SMTP filter window, click the button beside the SMTP Server Settings field, right-click the SMTP Servers node, and select Add an SMTP Server.
