无法通过 SMTP yandex 错误 553 发送邮件

Question

正在设置通过 smtp 发送邮件。

private String mailhost = "smtp.yandex.ru";
private String user;
private String password;
private Session session;

public static final String TAG = "GMailSender: ";

static {
    Security.addProvider(new JSSEProvider());
}

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

    Properties props = new Properties();
    props.setProperty("mail.transport.protocol", "smtp");
    props.setProperty("mail.host", mailhost);
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.port", "465");
    props.put("mail.smtp.starttls.enable","true");
    props.put("mail.smtp.ssl.enable", "true");
    props.put("mail.smtp.socketFactory.port", "465");
    props.put("mail.smtp.socketFactory.class",
            "javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.socketFactory.fallback", "false");
    props.setProperty("mail.smtp.quitwait", "false");

    session = Session.getDefaultInstance(props, this);
}

protected PasswordAuthentication getPasswordAuthentication() {
    return new PasswordAuthentication(user, password);
}

Answer 1

重述错误消息：

The user you log in with is not authorized to send email on behalf of the email address listed in the from field of the email (the sender).

这种安全措施用于防止您冒充他人发送垃圾邮件。
