Configuring the custom SURBL list for the Anti-Spam engine

You can create a custom SURBL list to improve the accuracy of spam detection. SURBL servers store lists of web addresses that were previously detected in the subject or body of messages recognized as spam and to which the Anti-Spam module assigns a spam rating and one of the Anti-Spam message scan status labels.

To create the custom SURBL list of the Anti-Spam engine:

1. In the main window of the program web interface, open the management console tree and select the Settings section and Protection subsection.
2. In the Anti-Spam section, click the Custom SURBL list link to open the Custom SURBL list window.
3. In the text box under the name of the Custom SURBL list window, type the DNS names of SURBL servers.

   You can use only these symbols: a–z, A–Z, 0–9, "-" and ".", and the "-" symbol must not come last. For example, you can add the DNS name dns-bl.example.com to the list.

   Enter each DNS name in a separate line.

4. Click the Apply button.
