Sending E-mail to an MSMQ Application

The e-mails submitted by MAPI client applications are routed through the MSMQ MAPI Transport Provider to the MSMQ application (see the following illustration). The MSMQ application can then pick up, process, and return the mail to the MAPI user who sent the mail or forward it (or another mail) to the next processing destination.

To send forms to an MSMQ application, the MSMQ MAPI Transport Provider performs the following tasks:

• Converts the e-mail form to an MSMQ mail message whose body is in MSMQ mail format.
• Sends the converted mail message to the MSMQ application input queue used by the MSMQ application.

The MSMQ application must create the application input queue. When creating the queue, the application must specify a queue type so that the MAPI Transport Provider can find the queue.
