Outbound Gateway

Gateway servers allow you to reduce the load on your primary server by using a secondary server to process outbound 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 outbound gateway settings, log into SmarterMail as a System Administrator and click on the Settings icon. Then select Gateways / Failover in the navigation pane. The Outbound tab will be highlighted, by default.

To add a new outbound gateway, click the New button. When adding or editing an entry, the following settings will be available:

Options

  • Server Address - The IP address of the gateway server.
  • Port - The port used to connect to the gateway server.
  • Encryption - Select the type of encryption from the list.
  • Status - The status of the outbound gateway. To temporarily turn off the outbound gateway, select Disable from the list.
  • Type - This sets the behavior of the gateway: it will either "Round Robin", meaning that when multiple gateways are configured, domains will use one then use the next to send mail, cycling through each gateway, or it's possible to set up a gateway to be used by "Specific Domains". When a gateway is set up to be used by Specific Domains, the gateway is selected FOR the domains when the domains are being set up. (Or, it's possible to set the gateway for a domain after it's been set up.)
  • Enable Authentication - Enable this setting if your outbound gateway server requires authentication. Then enter the Auth Username and Password below.
  • Auth Username - The authorized username of the gateway server.
  • Auth Password - The corresponding password for the authorized username.
