Prevent users from sending specific file types to instant messaging contacts using the BlackBerry Client for IBM Lotus Sametime

On BlackBerry devices that are running BlackBerry Device Software version 4.2 or later and the latest version of the BlackBerry Client for IBM Lotus Sametime, users can send files to their instant messaging contacts. To help manage network resources in your organization's environment, you can specify the types of files that users cannot send from their BlackBerry devices.
In the IT policy for a group or a specific user account, in the Instant Messaging policy group, in the Disallow File Transfer Types IT policy rule, perform one of the following actions:
  • To prevent users from sending specific file types, type the file extensions and separate them using commas. For example, type bat, exe, mp3 to prevent users from sending batch, executable, and mp3 files.
  • To prevent users from sending all file types, type an asterisk (*).
