Notes client and messages received from other Domino servers, as well as those from the Internet. Server mail rules are configured and stored on the server configuration document in the Domino directory. Server mail rules will be registered as monitors for all MAIL.BOX files in use on the server. Server mail rules can use the message header, the body of the message, or even the form which a mail message is using to determine whether to act on it. The combination of conditions and actions is large; this offers you absolute control over which messages are delivered in your environment. With these rules you can filter out known spam senders, messages that contain questionable content, or even prevent your own users from sending out a message to a large number of recipients. Enabling and implementing server mail rules can have a performance impact on your server, but if spam is a major problem in your organization, benefits will outweigh the costs. Configuration of server mail rules 1. In the Administration client, click the Configuration tab and expand the Messaging section. 2. Click Configurations. 3. Select the configuration settings document for the server you want to administer and click Edit Configuration. 4. Click the tabs in the following order: Router/SMTP → Restrictions and Controls → Rules. 46 Lotus Domino 6 spam Survival Guide for IBM eServer
