这段代码有什么问题？不知怎的,它进入了线路的无限循环 Transport.send(message);,没有错误信息,没有异常,只是可能无限循环(我不知道因为我不等待超过5-10分钟)

final String username = "<mail_name>";
final String password = "<password>";

Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "465");

Session session = Session.getInstance(props,
        new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(username, password);
            }
        });

try {

    Message message = new MimeMessage(session);
    message.setFrom(new InternetAddress("<mail_from>@gmail.com"));
    message.setRecipients(Message.RecipientType.TO,
            InternetAddress.parse("<mail_to>@gmail.com"));
    message.setSubject("Test Subject");
    message.setText("Test");

    Transport.send(message);

    System.out.println("Done");

} catch (MessagingException e) {
    throw new RuntimeException(e);
}

我试图从spring应用程序发送邮件.我已经包含了所有jar文件,但是它显示了这个异常:

我有gmail和yahoo工作,但不是hotmail.这就是我拥有的,我做错了什么？

private String mailhost = "smtp.live.com";

    public hotmailSenderActivity(String user, String password) {   
    this.user = user;   
    this.password = password;   

  //This connects to the actual mailserver
    Security.addProvider(new com.provider.JSSEProvider());
    Properties props = new Properties();   
    props.setProperty("mail.transport.protocol", "smtp");   
    props.setProperty("mail.host", mailhost); 
    props.put("mail.smtp.starttls.enable", "true");  
    props.put("mail.smtp.auth", "true");   
    props.put("mail.smtp.port", "587");   
    props.put("mail.smtp.socketFactory.port", "587");   
    props.put("mail.smtp.socketFactory.class",   
            "javax.net.ssl.SSLSocketFactory");   
    props.put("smtp.starttls.enable", "true");
    props.put("mail.smtp.socketFactory.fallback", "false");   
    props.setProperty("mail.smtp.quitwait", "false");   

    session = Session.getDefaultInstance(props, this);  

我尝试过端口25 + 587没有SSL的东西.我已尝试使用SSL端口465.电子邮件和密码是正确的(我已经硬编码确定).

我没有收到任何错误......那么问题是什么？

我无法使用Java Mail API从Yahoo ID发送电子邮件。我尝试了Google提供的其他选项，但失败了。请查看下面的代码，如果我缺少什么，请告诉我。以我的观点，雅虎不提供免费的发送邮件服务，但我不确定。请提供您对此的想法。

import javax.mail.internet.*;

public class MailExample {
    private static final String SMTP_HOST_NAME = "smtp.mail.yahoo.com";
    private static final int SMTP_HOST_PORT = 587;//465,587,25
    private static final String SMTP_AUTH_USER = "dummyrls@yahoo.com";
    private static final String SMTP_AUTH_PWD  = "my password";

    public static void main(String[] args) throws Exception{
