Question

我一直尝试从试图登录到Outlook服务器的自定义域发送电子邮件，因为我们将其用作从该方向发送电子邮件的平台，但是它给了我{{1} };更具体地说：

AuthenticationFailedException

我一直在寻找一些较旧的文章，这些文章可能是解决我的问题的方法，但是我不知道如何在我的代码中实现它。

我的代码如下：

javax.mail.AuthenticationFailedException: 535 5.7.3 Authentication unsuccessful [PR0P264CA0272.FRAP264.PROD.OUTLOOK.COM]

    at com.sun.mail.smtp.SMTPTransport$Authenticator.authenticate(SMTPTransport.java:965)
    at com.sun.mail.smtp.SMTPTransport.authenticate(SMTPTransport.java:876)

我已经更改了代码以实现spring框架库，以便可以同步发送邮件。这是现在的样子：

    String to = "to@mail.com";
    String from = "from@cdomain";
    String password = "password123";
    String subject = "Hello";
    BodyPart body1 = new MimeBodyPart();
    String body= "This is an e-mail";
    body1.setText(body);
    Multipart mainBody = new MimeMultipart();
    mainBody.addBodyPart(body1);
    
    String host = "outlook.office365.com";
    Properties properties = System.getProperties();
    properties.put("mail.smtp.host", host);
    properties.put("mail.smtp.starttls.enable", "true");
    properties.setProperty("mail.smtp.auth", "true");
    Session session = Session.getInstance(properties, new OutLookAuthenticator(from, password));
    Transport transport = session.getTransport("smtp");
    Message message = new MimeMessage(session);
    message.setSubject(asunto); 
    message.setContent(mainBody);
    message.setFrom(new InternetAddress(from));
    InternetAddress[] address = {new InternetAddress(to)};

    message.setRecipient(Message.RecipientType.TO, new InternetAddress(to));
         
    transport.send(message);

现在，它正在打印此堆栈跟踪：

            JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
            mailSender.setHost("outlook.office365.com");
            mailSender.setPort(587);
            String from = keyboard.nextLine();
            mailSender.setUsername(from);
            String password = readPassword();
            mailSender.setPassword(password);

            MimeMessage message = mailSender.createMimeMessage();

            final Properties properties = new Properties();
            properties.put("mail.smtp.auth", Boolean.TRUE);
            properties.put("mail.smtp.starttls.enable", Boolean.TRUE    );
            mailSender.setJavaMailProperties(properties);
            
            try {
            final MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setFrom(from);
            helper.setTo(to);
            helper.setSubject(subject);
            helper.setText(text, true);
            } catch (MessagingException e) {
                e.printStackTrace();
            }
            mailSender.send(message);

看来您的凭证错误，或者托管项目的服务器可能阻塞了某些传出端口。例如，数字海洋默认情况下会阻塞25端口。
但是，您可以在此处找到同步发送邮件的解决方案。
其中this.getUsername()，this.getPassword()，this.getPort()，this.getHost()作为您的（邮件服务器）凭据。
如果您也想在邮件中发送HTML，请参阅.setText()，该参数将Boolean参数作为第二个参数。

P.S 顺便说一句，我建议您以新的Thread格式发送，因为它需要时间来发送，然后无论是否成功，都会收到响应。但是，这确实取决于您的业务逻辑。

    JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
    mailSender.setHost(this.getHost());
    mailSender.setPort(this.getPort());
    mailSender.setUsername(this.getUsername());
    mailSender.setPassword(this.getPassword());

    MimeMessage message = mailSender.createMimeMessage();

    final Properties properties = new Properties();
    properties.put("mail.smtp.auth", Boolean.TRUE);
    properties.put("mail.smtp.starttls.enable", Boolean.TRUE);
    mailSender.setJavaMailProperties(properties);

    final MimeMessageHelper helper = new MimeMessageHelper(message, true);
    helper.setFrom(fromMail);
    helper.setTo(user.getEmail());
    helper.setSubject(subject);
    helper.setText("<p><strong>Welcome " + body + ",</strong></p>\n", true);
    mailSender.send(message);
