# Server Configuration Tab

The Server Configuration tab enables you to configure server parameters such as:

- License Key: this is the product key. Without this value, Commtouch cannot provide outbound spam protection.

- Server Addres s: this is the service server address and is mandatory. The default value is: resolver%d.plesk.ctmail.com

- Enable Outbound Filtering: The Commtouch solution was designed to protect against both incoming and outgoing spam attacks. By enabling this parameter (the default setting), Commtouch’s Outbound Anti-Spam filtering solution is enabled.

- Bypass on errors: Enable this parameter if you want bypass the Outbound Protection service and accept messages, when the solution returns an error. If this parameter is not enabled, when Commtouch returns an error, the message is temporarily delayed (tempfail).
