我正在开发一个 Java 应用程序，我正在使用 Javamail 发送邮件。我的代码如下：

Properties props = new Properties();
props.put("mail.smtp.host", "diana.cartif.es");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");

Session session = Session.getDefaultInstance(props,
    new javax.mail.Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication("alerts","pass");
        }
    });

Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("alerts@cartif.es"));
message.setRecipients(Message.RecipientType.TO,InternetAddress.parse("campus21@cartif.es"));
message.setSubject("Testing Subject");
message.setText("Dear Mail Crawler," +"\n\n No spam to my email, please!");

Transport.send(message);

但是，当我执行此代码时，它会引发异常：

javax.mail.MessagingException: Could not connect to SMTP host: diana.cartif.es, port: 465, response: -1
    at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1960)
    at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:642)
    at javax.mail.Service.connect(Service.java:317)
    at javax.mail.Service.connect(Service.java:176)
    at javax.mail.Service.connect(Service.java:125)
    at javax.mail.Transport.send0(Transport.java:194)
    at javax.mail.Transport.send(Transport.java:124)
    at com.cartif.data.MainConnection.getFTPConnection(MainConnection.java:106)
    at com.cartif.main.Main.connectToServer(Main.java:72)
    at com.cartif.main.Main.main(Main.java:60)

要连接的数据是正确的，因为我在我的邮件服务器中检查了它。有人可以帮我吗？

谢谢！

尝试可能是这样的：

     String  d_email = "email",
             d_password = "pass";

    Properties props = new Properties();
    props.put("mail.smtp.host", "smtp.server");
    props.put("mail.smtp.user", d_email);
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.port", port);

    Authenticator auth = new SMTPAuthenticator();
    Session session = Session.getInstance(props, auth);

摆脱 socketFactory* 属性。在大多数情况下，它们不再需要并添加

props.put("mail.smtp.ssl.enable", true);

尝试调用：

session.setDebug(true);

看看你是否有任何帮助。

最后，我用以下属性解决了这个问题：

props.setProperty("mail.smtp.host", "smpt.host");
props.setProperty("mail.smtp.starttls.enable", "false");
props.setProperty("mail.smtp.port","25");
props.setProperty("mail.smtp.user", "alerts");
props.setProperty("mail.smtp.auth", "true");

Session session = Session.getDefaultInstance(props);
session.setDebug(true);

MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress("mail1@mail.es"));
message.addRecipient(Message.RecipientType.TO, new InternetAddress("mail2@mail.es"));
message.setSubject("Subject");
message.setText("Text");

Transport t = session.getTransport("smtp");
t.connect("user","pass");
t.sendMessage(message,message.getAllRecipients());
t.close();
