How to send messages via smtp yandex?

Question

Java

Good day! The problem is the following, you need to send letters from the mailbox, it is located on yandex, I try this

the code

String to = "[email protected]";         // sender email
        String from = "[email protected]";       // receiver email

        Properties properties = System.getProperties();
        properties.setProperty("mail.smtp.host", "smtp.yandex.ru");
        properties.setProperty("mail.smtp.port", "465");
        properties.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        properties.setProperty("mail.smtp.socketFactory.port", "465");
        properties.setProperty("mail.smtp.auth", "true");


        Session session = Session.getInstance(properties,new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("[email protected]","senderPasswd");
            }
        }); // default session

        try {
            MimeMessage message = new MimeMessage(session); // email message

            message.setFrom(new InternetAddress(from)); // setting header fields

            message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));

            message.setSubject("Test Mail from Java Program"); // subject line

            // actual mail body
            message.setText("Some Message");

            // Send message
            Transport.send(message); System.out.println("Email Sent successfully....");
} catch (MessagingException mex){ mex.printStackTrace(); }

but I get

exception

com.sun.mail.smtp.SMTPSendFailedException: 553 5.7.1 Sender address rejected: not owned by auth user.

how to fix it?
Thanks in advance!

Answer 1

So, it seems that I understand what the problem is:
javatalks.ru/topics/17071?page=1#81943
Here they write that Yandex does not allow FROM, but they say that the solution "SMTPMessage.setEnvelopeFrom will not help? SMTP perfectly allows you to replace all this. "
If there is a code, so to speak, the original one, then replace the login-password and mail.

agree - for freemyl, which Yandex is - the ability to spam on behalf of another Yandex user is critical, the rest will look like and the original
