java - SMTP地址失败异常 : 550-Verification failed

Question

我正在使用以下代码使用java发送电子邮件

 function send(){
   String host1 = "domainname";
   String to = "test@domain.com";
   String from="dontreply@domain.com";
   String subject = "test mail";
   String messageText = "test content";
   boolean sessionDebug = false;
   Properties props = System.getProperties();
   props.put("mail.host", host1);
   props.put("mail.transport.protocol", "smtp");
   Authenticator authenticator = new Authenticator();
   Session mailSession = Session.getInstance(props, authenticator);



       mailSession.setDebug(sessionDebug);
           Message msg = new MimeMessage(mailSession);
   msg.setFrom(new InternetAddress(from));
   InternetAddress[] address = {new InternetAddress(to)};
   msg.setRecipients(Message.RecipientType.TO, address);
   msg.setSubject(subject);
   //msg.setSentDate(new Date());
   msg.setContent(messageText,"text/html");
   Transport.send(msg);
   }
   private class Authenticator extends javax.mail.Authenticator implements java.io.Serializable {
    private PasswordAuthentication authentication;

    public Authenticator() {
         String username = "support@domain.com";

        String password = "**********";
        authentication = new PasswordAuthentication(username, password);
    }
    protected PasswordAuthentication getPasswordAuthentication() {
        return authentication;
    }
}

工作正常。但现在我需要更改发件人地址“someother@domain.com”，并且我必须使用与以前相同的身份验证详细信息发送邮件。如果我只是使用相同的身份验证更改我的发件人地址，则会收到以下错误:

exceptionjavax.mail.SendFailedException: Invalid Addresses;
  nested exception is:
    com.sun.mail.smtp.SMTPAddressFailedException: 550-Verification failed for <someother@domain.com>
550-No Such User Here"
550 Sender verify failed

是否可以使用相同的身份验证和不同的地址发送邮件......

谁能帮我解决这个问题......

我怀疑有一些配置或策略会阻止未注册 from 地址的外发邮件。如果您的问题是配置用户可以回复的地址(并且该地址应该与您正在验证的地址不同)，那么您可以设置一个 reply-to header 。
