Use the Add IP Block List Provider control on the Providers tab to add IP Block List provider services for the local computer.

  • Provider name
    In this field, type the name of the IP Block List provider service. This name is for your own use to identify the provider.
  • Lookup domain
    In this field, 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 as a match. When 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 services may return different types of codes. Most IP Block List provider services return one of the following code types: bitmask or absolute value.

    When you select Return Status codes, the Connection Filter agent acts only on messages that match the same IP Address status code that is returned by the IP Block List provider service. The following examples show absolute values and the explicit 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 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 to the following mask
    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. For providers that return bitmask status codes, type **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.

  • Match to any of the following responses
    When you select this option, the Connection Filter agent acts only on messages that match the same IP address status code that is returned by the IP Block List provider service. The following examples show absolute values and the explicit 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.
