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:

MAPI Client and CDO 1.2.1

The Socket API requires Microsoft Exchange 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. We recommend using the latest build, which is unrelated to the 1.2.1 version number.

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

Note: In previous releases, we recommended 'MAPI client and CDO 1.2.1' or Microsoft Outlook. We have now withdrawn this recommendation. Instead, you must use 'MAPI client and CDO 1.2.1'.
