Socket API Requirements

The Socket API requires the Messaging API (MAPI) client libraries to pass email data to a policy engine or PE hub. If this functionality is not available, the Socket API cannot process emails received from the NBA or Milter MTA agent. Therefore, the Socket API host server requires either the "Messaging API and Collaboration Data Objects 1.2.1" or Microsoft Outlook.

Note: We recommend that you always use the "Messaging API and Collaboration Data Objects 1.2.1" component.

Server "Messaging API and Collaboration Data Objects 1.2.1"

This software is typically referred to as the "MAPI client and CDO 1.2.1" component.

Download the "MAPI client and CDO 1.2.1" component from the Microsoft Web site.

Important: Before you install this component, verify that Microsoft Outlook is not also installed. If Outlook is already installed, uninstall it.

Microsoft Outlook (32-bit only)

Outlook must be the default email application on the host machine. Note also that 64-bit Outlook is not compatible with the Socket API.
