Javamail 535 5.7.8身份验证失败 [英] Javamail 535 5.7.8 authentication failed

问题描述

我正在使用javamail api发送邮件.

I'm using javamail api to send mails.

以下代码已经运行了大约5个月:

The following code has been working for about 5 months:

public static void sendMail(String dest, String oggetto, String testoEmail, String[] filePath) throws MessagingException{
    String sender2="mymail";
    String passSender2="mypass";
    String smpt2="smpt server";
    String port2="25";
    Properties props = new Properties();
    props.put("mail.smtp.port", port2);  //imposta la porta
    props.put("mail.smtp.host", smpt2);
    props.put("mail.smtps.auth", "true");
    props.put("mail.debug", "true");
    props.put("mail.smtp.starttls.enable","true");  //imposta la connessione cifrata





    Session session = Session.getDefaultInstance(props, null);

    MimeMessage message = getMessage(filePath, oggetto, session, testoEmail);


    InternetAddress fromAddress = new InternetAddress(sender2);
    InternetAddress toAddress = new InternetAddress(dest);
    message.setFrom(fromAddress);
    message.setRecipient(Message.RecipientType.TO, toAddress);
    Transport transport = session.getTransport("smtp");
    transport.connect(smpt2, 25, sender2, passSender2);

    transport.sendMessage(message, message.getAllRecipients());
    transport.close();
}

但是现在我得到了这个错误:

But now i get this error:

535 5.7.8 Error: authentication failed: authentication failure

我尝试使用

props.put("mail.smtp.auth.mechanisms", "VALUE" );

使用Value ="LOGIN"或value ="PLAIN"或value ="DIGEST-MD5"或value ="CRAM-MD5"，但没有任何效果. 我试图通过网络邮件发送电子邮件，但该电子邮件仍然有效，因此我的帐户未关闭，并且我的凭据正确.

with Value="LOGIN" or value="PLAIN" or value="DIGEST-MD5" or value="CRAM-MD5" but nothing worked. I tried to send an email through the webmail and it worked, so my account is not closed, and my credentials are right.

这是调试跟踪:

您有什么主意吗?

推荐答案

尝试将Session.getDefaultInstance更改为Session.getInstance.

Try changing Session.getDefaultInstance to Session.getInstance.

如果这样做没有帮助，请提供更多显示故障的调试输出.

If that doesn't help, include more of the debug output showing the failure.
