Aşağıda ki adımları izleyerek Edge tarafında IP bazlı engelleme işlemlerini yapabilirsiniz.

  1. In the console tree, click Edge Transport.
  2. In the result pane, click the Edge server you want to configure and then select the Anti-spam tab in the work pane.
  3. Right-click IP Block List Providers and then select Properties.
  4. The General tab displays the following information about the IP Block List Providers feature.
    • Status   Shows whether the IP Block List Providers feature is enabled or disabled.
    • Modified   Shows the date and time when IP Block List Providers properties were last modified.
    • Description   Provides a brief description of the IP Block List Providers feature.
  5. Use the Providers tab to manage the IP Block List provider services for the local computer. We recommend that you put the most reliable IP Block List provider service first to optimize performance. If the Connection Filter agent receives an IP Block List match from one of the providers, it stops querying other IP Block List provider services.
    • Add   Click Add to add a new IP Block List provider service. In the dialog that appears, configure the following options:
      Provider name   Type the name of the IP Block List provider service. This name is for your own use to identify the provider.
      Lookup domain   Type the domain name that the Connection Filter agent queries for updated IP Block list information.
      Return Status codes   This field shows the IP address status code that is returned by the IP Block List provider service. If the IP address of a remote server that is sending a message matches an IP address on an IP Block List provider service’s IP Block list, the provider service may return different types of codes. Most IP Block List provider services return either a bitmask or absolute value code type.
      Match any return code   When you select this option, the Connection Filter agent treats any IP Address status code that is returned by the IP Block List provider service as a match.
      Match specific mask and responses   When you select this option, the Connection Filter agent acts only on messages that match the IP Address status code that is returned by the IP Block List provider service.
      Providers that return bitmask status codes may return a status code of 127.0.0.x, where the integer x is any one of the following values:
      1: The IP address is on an IP Block list.
      2: The Simple Mail Transfer Protocol (SMTP) server is configured to act as an open relay.
      4: The IP address supports a dial-up IP address.
      Providers that return absolute values and the explicit responses may return one of the following responses:
      127.0.0.2: The IP address is a direct spam source
      127.0.0.4: The IP address is a bulk mailer
      127.0.0.5: The remote server that is sending the message is known to support multistage open relays.
      Match to the following mask   Type the bitmask status code you want to use.
      Match any of the following responses   Type the responses you want to use and then click Add. To modify a previously added response, select the response and click Edit. To remove a previously added response, select the response and click Remove icon.
      Error Messages   To configure the message text that will be delivered in the SMTP session to senders whose messages are blocked by the Connection Filter agent when an IP Block List provider service matches the sender’s IP address, click Error Messages and configure the following:
