javaMail发送问题

Question

public String sendMail(String mailFrom,String mailTo,String subject,String content) {
String result="false";
try {
Properties prop = System.getProperties();
prop.put("mail.pop3.host", "163.net");
Session session = Session.getDefaultInstance(prop, null);
MimeMessage msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(mailFrom));
msg.setRecipient(Message.RecipientType.TO, new InternetAddress(mailTo));
msg.setSubject(subject);
msg.setSentDate(new Date());
msg.setText(content);
Transport.send(msg);
result="true";
return result;
} catch (Exception e) {
System.out.println("sendMail : "+"send failed !");
e.printStackTrace();
return result;
}
}
总是会发送失败
prop.put("mail.stmp.host", "163.net");
这里mail.stmp.host我改成pop3的也是发送失败。
