我有下一个问题,发送带有Java的电子邮件,我不知道为什么。做调试我得到了这个,我不知道为什么。跟踪错误的痕迹是:

执行此操作的代码是这样的,只是它是一个简单的函数,我这样做:
String[] lista_envio = enviar_a.split(";");
String smtpHost = "smtp.businesscloud.es";
Properties props = System.getProperties();
props.put("mail.smtp.host",smtpHost);
props.put("mail.smtp.port", 465);
props.put("mail.smtp.user", "");
props.put("mail.smtp.password","");
props.put("mail.debug", "true");
Session sesion = Session.getDefaultInstance(props,null);
Message correo = new MimeMessage(sesion);
correo.setSubject(asunto.trim().toUpperCase());
correo.setFrom(new InternetAddress(enviado_por));
for (int i = 0; i < lista_envio.length; i++)
{
System.out.println("Dentro del for de enviar_correos");
correo.addRecipient(Message.RecipientType.TO, new InternetAddress(lista_envio[i]));
}
correo.setText(cuerpo);
correo.addHeader("X-Priority", "3");
System.out.println("Voy a mandar el mail");
Transport.send(correo);
发送后的例外情况是:未知的SMTP主机:smtp.businesscloud.es,很奇怪。
我做错了什么?非常感谢
