Outgoing Gateway

Gateway servers allow you to reduce the load on your primary server by using a secondary server to process outgoing mail. Gateway servers can also be used to combat blacklisting. If the gateway server gets blacklisted, simply rotate the primary IP on the network card to a different one to send out on the new IP.

To access the outgoing gateway settings, click the settings icon. Then expand the Routing folder and click Outgoing Gateways in the navigation pane. A list of outgoing gateways will load in the content pane.

To add a new outgoing gateway, click New in the content pane toolbar. To edit an existing gateway, select the desired gateway and click Edit. The outgoing gateway settings will load in the content pane and the following tabs will be available:


Use this tab to specify the following settings:

  • Server Address - The IP address of the gateway server.
  • Port - The port used to connect to the gateway server. By default, the port is 25.
  • Auth Username - The username of the gateway server given to you by your ISP.
  • Auth Password - The password for your gateway server.
  • Encryption - Select the type of encryption from the list.
  • Priority Range - The priority range for this server. System administrators can use gateway servers to only send mails with a certain priority level. For example, gateways can be used only for lower priority messages, such as newsletters or messages over a certain size, to reduce load and free up processing on the primary mail server.
  • Enable SmarterMail gateway mode - Select this option to indicate that the outgoing gateway server is another SmarterMail server.
  • Description - A friendly name or brief description of the gateway.
