How to Enable Connection Filtering

 

Topic Last Modified: 2007-01-22

When you enable connection filtering on an SMTP virtual server, e-mail messages received from any IP address matched by a connection filtering rule or e-mail messages from an IP address specified on the global deny list are not accepted.

Connection filtering is defined globally, but enabled at the SMTP virtual server on a per-IP address basis. Different groups of users can log on with any number of IP address/TCP port combinations. You can decide which combinations, and therefore which users or groups will have connection filtering enabled for their messages.

noteNote:
Before you can enable connection filtering on a virtual server, you must create a connection filter. The topic, How to Create an Intelligent Message Filter, provides guidelines for doing this.

  1. Start System Manager: On the Start menu, point to Programs, point to Microsoft Exchange, and then click System Manager.

  2. Move to the SMTP virtual server, starting with Server.

  3. Right-click the SMTP virtual server, and then click Properties.

  4. On the General tab, click Advanced.

  5. In Advanced, select the IP address to which you want to apply the connection filtering, and then click Edit.

  6. In Identification, select the Apply Connection Filter check box, and then click OK. In Advanced, under the Filter Enabled column, Yes appears.

  7. To disable filtering, clear the Apply Connection Filter check box.
