Answer 1

si se golpea el UnknownHostException: smtp.gmail.com, tratar smtp.gmail.com ping y asegurarse de que tiene una respuesta (acceder a). Muchas veces, su conexión puede bloquear su servidor de seguridad o proxy. De lo contrario, necesita javaee.jar y mail.jar en su classpath.

Answer 2

Intente por estas propiedades de correo. Verifique que su correo se envíe correctamente.

Properties props = new Properties(); 
props.put("mail.smtp.host", "smtp.gmail.com"); 
props.put("mail.smtp.starttls.enable", "true"); 
props.put("mail.smtp.auth", "true"); 
props.put("mail.smtp.port", "587");
