java - 使用 gmx smtp 服务器和 java 邮件

Question

我想使用gmx smtp服务器用java邮件发送一些邮件。我得到的只是这个异常，我应该在异常中查看的页面没有向我提供如何解决此问题的信息。

com.sun.mail.smtp.SMTPSendFailedException: 553 5.1.7 Complete address with domain, please ( http://portal.gmx.net/serverrules ) {mp032}
;
  nested exception is:
        com.sun.mail.smtp.SMTPSenderFailedException: 553 5.1.7 Complete address with domain, please ( http://portal.gmx.net/serverrules ) {mp032}

我用Java实现它如下:

props = new Properties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.host", "mail.gmx.net");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
props.put("mail.from", "test@test.test);
props.put("username", "SOMEUSERNAME@gmx.at");
props.put("password", "SOMEPASS");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.debug", "true");

Authenticator auth = new SMTPAuthenticator(props.getProperty("username"), props.getProperty("password"));


    if ("true".equals(smtp.getSmtpAuth())) {
        mailSession = Session.getDefaultInstance(props, auth);
    } else {
        mailSession = Session.getDefaultInstance(props);
    }


}

class SMTPAuthenticator extends Authenticator {

    private String username, password;

    public SMTPAuthenticator(String username, String password) {
        this.username = username;
        this.password = password;
    }

    @Override
    public PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(username, password);
    }
}

以下是使用 GMX 发送电子邮件的工作代码:

public static void sendGMX() throws MessagingException
{
    String sender = "my.email@gmx.de";
    String password = "my.password";
    String receiver = "my-receiver@gmail.com";

    Properties properties = new Properties();

    properties.put("mail.transport.protocol", "smtp");
    properties.put("mail.smtp.host", "mail.gmx.net");
    properties.put("mail.smtp.port", "587");
    properties.put("mail.smtp.auth", "true");
    properties.put("mail.smtp.user", sender);
    properties.put("mail.smtp.password", password);
    properties.put("mail.smtp.starttls.enable", "true");

    Session mailSession = Session.getInstance(properties, new Authenticator()
    {
        @Override
        protected PasswordAuthentication getPasswordAuthentication()
        {
            return new PasswordAuthentication(properties.getProperty("mail.smtp.user"),
                    properties.getProperty("mail.smtp.password"));
        }
    });

    Message message = new MimeMessage(mailSession);
    InternetAddress addressTo = new InternetAddress(receiver);
    message.setRecipient(Message.RecipientType.TO, addressTo);
    message.setFrom(new InternetAddress(sender));
    message.setSubject("The subject");
    message.setContent("This is the message content", "text/plain");
    Transport.send(message);
}

注意

You have to manually enable POP3/IMAP support in your e-mail account否则您仍然会收到 AuthenticationFailedException 异常:

Exception in thread "main" javax.mail.AuthenticationFailedException: 535 Authentication credentials invalid
