Firewall Block Incoming Messages IT policy rule


This rule specifies whether the BlackBerry® device firewall prevents the BlackBerry device from processing specific types of incoming messages, including SMS text messages, MMS messages, public and organization-specific PIN messages, and BlackBerry® Internet Service messages.

Note: You use the default PIN encryption key to send public PIN messages that are known to all BlackBerry devices. A BlackBerry device with an organization-specific PIN encryption key can only send and receive organization-specific PIN messages with other BlackBerry devices within your organization's network that use the same PIN encryption key.

Default value

The default value is a null value.


If you configure this rule, a BlackBerry device blocks the specified types of incoming messages at the firewall and does not notify the user that those types of messages were received.

A user can specify whether to block public PIN messages on a BlackBerry device. A user cannot specify whether to block organization-specific PIN messages on a BlackBerry device.

  • Java® based BlackBerry device
  • BlackBerry® Application Suite version 1.0
