Data flow: Receiving email on an 
iOS
 device using the 
BlackBerry Secure Gateway

This data flow describes how work email and calendar data travels between 
iOS
 devices and the 
Exchange ActiveSync
 server using the 
BlackBerry Secure Gateway
.
Diagram showing the steps and components mentioned in the following data flow.
  1. The native email client on iOS maintains a permanent connection with the email server over an encrypted and authenticated channel between the 
    BlackBerry Infrastructure
     and the 
    BlackBerry Secure Gateway
     and detects changes in the folders configured for synchronization on the mail server.
  2. When there are new or changed items for the device, such as a new email message or updated calendar entry, the mail server sends the updates to the device through the secure channel between the 
    BlackBerry Secure Gateway
     and the 
    BlackBerry Infrastructure
     to the email or organizer app on the device using the 
    Exchange ActiveSync
     protocol.
