Administration Guide Managing instant messaging Managing instant messaging features 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 (*). Related information Change the value for an IT policy rule, 46 Specifying the maximum size of file types that users can send using the BlackBerry Client for IBM Lotus Sametime To control the use of network resources in your organization's environment, you can use the media content management feature to specify the maximum size of specific file types that BlackBerry device users can send to each other using the BlackBerry Client for IBM Lotus Sametime. The maximum file size that you specify for a file type must not exceed the maximum file size that you specified on the IBM Lotus Sametime server.
