Incoming Gateways

The purpose of an incoming gateway is to reduce server load. Generally, spam checks and antivirus scans should be performed on the incoming gateway, freeing up the primary server processing for the delivery of messages.

To access the incoming gateway settings, log into SmarterMail as a System Administrator and click on the Settings icon. Then click on Gateways / Failover in the navigation pane and select the Incoming tab.

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

Options

  • Gateway Mode - The function that the incoming gateway will perform. If the incoming gateway is set to Backup MX, it will only receive messages when your primary server is down. If the incoming gateway server is set to Domain Forward, it will receive all messages and forward them to your primary server.
  • IP Addresses (single or range) - The IP address, or range of IP addresses, of the primary mail server.
  • Status - New gateways default to a status of Enabled. To temporarily stop an incoming gateway, you can change the stuats to Disabled.
  • SMTP User Verification -

Domains

This card is only available if the gateway mode is set to Domain Forward. Domain forwarding allows you to easily send mail through one server to another. This will allow your server to act as an incoming gateway to your network, and permit you to have a single point of entry for incoming SMTP traffic.

When messages come in to a forwarded domain, they are run through the command-line exe referenced in the Protocols settings. If a delivery delay has been established for the server, messages are also delayed accordingly. This allows you to establish an incoming server that can run external virus or spam scanners, which can reduce the load on your existing network servers.

Use this card to specify for which domains the incoming gateway will accept mail:

  • Domain Verification - The method used by the incoming gateway to determine if a domain is valid or not: Specified Domains or All But Specified Domains. List the domain(s) below (one entry per field).

SmarterMail Gateway

  • Enable SmarterMail Gateway Mode - Select this option to indicate that the incoming gateway server is another SmarterMail server.
  • SmarterMail URL - The Webmail URL for the SmarterMail server being used an an incoming gateway. This will allow the use of Web services to verify the users and domains.
  • SmarterMail Username - The identifier used to login to the primary mail server.
  • SmarterMail Password - The corresponding password used to login to the primary mail server.
  • User Verification - The method used by the incoming gateway to determine if a user is valid or not. Note: If none is selected, the incoming gateway server will accept all email addresses for the domain. If Web service is selected, the incoming gateway will check with the primary mail server for a list of valid email addresses.

Spam

Use this tab to specify the following spam checks:

  • Not Spam Action - The action the incoming gateway will perform on messages NOT marked as spam.
  • Spam Low Action - The action the incoming gateway will perform on messages with a low probability of being spam.
  • Spam Medium Action - The action the incoming gateway will perform on messages with a medium probability of being spam.
  • Spam High Action - The action the incoming gateway will perform on messages with a high probability of being spam.
