System and method for determining a security encoding to be applied to outgoing messages

A device comprising a processor is disclosed herein. In one broad aspect, the processor is configured to: determine whether a general message encoding configuration setting at the device is set to a first setting indicating that when a security encoding is to be applied to a message, the security encoding is to be established by a policy engine, wherein the established security encoding cannot be overridden by a security encoding selection algorithm at the device; and if the general message encoding configuration setting is set to the first setting, transmit the message to at least one message recipient via the policy engine such that the policy engine applies the security encoding to the message prior to the policy engine transmitting the message.
