Your BlackBerry smartphone is designed to use the default signing and encryption option when you send a message to a contact that you haven't previously sent a message to or received a message from. Otherwise, your smartphone uses the message history to suggest a signing and encryption option.
You can set your smartphone to try to use the default signing and encryption option for your outgoing messages instead. However, if message classifications are turned on, the default signing and encryption option might not be able to be used depending on the security requirements of a message's classification. For example, if your default signing and encryption option is set to Sign and you compose a reply to a message that is classified as confidential, the signing and encryption option is set to Sign and Encrypt instead of the default signing and encryption option.
