Any knows if it possible include variables in an annotation in BrigthMail. The idea is include a personal annotation, that said like "This message was sent by user_mail to recipient, any other people must be discard this message". Where user_mail is the sender and recipient is the recipient, this information could obtain from the message itself. According the sample in Privacy annotation this is not possible, but any could be know it.
