Opcion de marcar como SPAM

Estoy utilizando K-9 Mail Versión: 5.600.
No hay opción de marcar correos como SPAM. Existe alguna versión que lo permita ?

What do you want to happen if you mark the message as spam? K9 doesn’t contain the kind of spam filter that needs training. And if your mail provider provides a spam folder whose contents train their spam filter there is no good way to automatically determine how they did name this folder. But you can use k9’s move function in that case.
