Configuring SURBL options
In addition to supporting Fortinet’s FortiGuard Antispam SURBL service, the FortiMail unit supports third-party Spam URI Realtime Block Lists (SURBL) servers. You can specify which public SURBL servers to use as part of an antispam profile. Consult the third-party SURBL service providers for any conditions and restrictions.
The SURBL section of antispam profiles lets you configure the FortiMail unit to query one or more SURBL servers to determine if any of the uniform resource identifiers (URI) in the message body are associated with spam. If a URI is blocklisted, the FortiMail unit treats the email as spam and performs the associated action. There are two types of URIs. For details, see
“URI types”.
To configure SURBL scan options
1. When configuring an antispam profile, enable SURBL in the AntiSpam Profile dialog.
2. From Action, select the action profile that you want the FortiMail unit to use if the SURBL scan finds spam email.
3. Next to SURBL click Configuration.
A pop-up window appears that displays the domain name of the SURBL servers.
4. To add a new SURBL server address, click New and type the address in the field that appears.
Since the servers will be queried from top to bottom, you may want to put the reliable servers with less traffic to the top of the list. Click the drop-down menu in the title bar to sort the entries.
5. Select a server and click OK.
The pop-up window closes.
6. Continue to the next section, or click Create or OK to save the antispam profile.
