[. . . ] The BlackBerry Dispatcher sends the delivery confirmation to the BlackBerry Messaging Agent. If the BlackBerry Messaging Agent does not receive a delivery confirmation within four hours, it sends the message to the wireless network again. The delivery confirmation verifies that the wireless network delivered the message to the BlackBerry device, but it does not verify that the user received or opened the message. The BlackBerry device decrypts and decompresses the message so that the user can view it, and notifies the user that the message has arrived. 3. 7. 8. 41 Feature and Technical Overview Messaging process flows Process flow: Sending a message from a BlackBerry device This process flow applies to new messages, reconciled messages (messages that are moved, deleted, or marked as read or unread), and wireless calendar entries. If the message is a meeting invitation or calendar entry, the BlackBerry device appends the calendar information to the message. The BlackBerry device compresses and encrypts the message, and sends the message to the wireless network over port 3101. The wireless network sends the message to the BlackBerry® Enterprise Server. The BlackBerry Enterprise Server accepts only encrypted messages from the BlackBerry device. The BlackBerry Dispatcher uses the master encryption key of the BlackBerry device to decrypt and decompress the message. If the BlackBerry Dispatcher cannot decrypt the message using the master encryption key, the BlackBerry Enterprise Server ignores the message and sends an error message to the BlackBerry device. The BlackBerry Messaging Agent sends the message to the user's email application. The BlackBerry Messaging Agent sends a copy of the message to the Sent Items view in the user's email application. 7. Process flow: Sending a message that contains an attachment from a BlackBerry device 42 Feature and Technical Overview Messaging process flows 1. A user attaches a file to a message on a BlackBerry® device and sends the message. · If the BlackBerry device is not running BlackBerry® Device Software Version 4. 2 or later, and if the BlackBerry device does not have a CMIME service book that indicates that the BlackBerry® Enterprise Server supports attachment uploads, the Add Attachment menu item does not appear on the BlackBerry device. · If the user tries to attach a file that exceeds the maximum file size that an administrator specified, a notification appears and the user cannot attach the file. The BlackBerry device compresses and encrypts the message, and sends the message to the wireless network over port 3101. The BlackBerry device formats the header of the message to indicate that a large attachment is part of the message, but it does not send the attachment content. The wireless network sends the message to the BlackBerry Enterprise Server. The BlackBerry Dispatcher decrypts and decompresses the message with the master encryption key of the BlackBerry device. If the BlackBerry Dispatcher cannot decrypt the message with the master encryption key, the BlackBerry Enterprise Server ignores the message and sends an error message to the BlackBerry device. The BlackBerry Messaging Agent stores the message properties in the user's mailbox.
