%r words not yet used by %s; e.g., if the message is "FOO BAR FOOBAR BAZ", and the has been one %s, %r will mean "FOOBAR BAZ".

%a all words of the SMS message, including the first one.

%t the time the message was sent, formatted as "YYYY-MM-DD HH:MM", e.g. "1999-09-21 14:18"

%p the phone number of the sender of the SMS message

%P the phone number of the receiver of the SMS message
