Javamail-从localhost发送，而不是Goaddy服务器

Question

当我试图从“smtpout.asia.secureserver.net”发送邮件时，它是从本地主机而不是“secureserver”主机发送的。下面是代码:

Properties props = new Properties();    
             props.put("mail.smtp.host","smtpout.asia.secureserver.net");       
             props.put("mail.smtp.socketFactory.class",    
                       "javax.net.ssl.SSLSocketFactory");    
             props.put("mail.smtp.auth", "true");    
             props.put("mail.smtp.port", "465");
             props.put("mail.smtp.starttls.enable","true");
             props.put("mail.debug", "true"); 

 Session session = Session.getDefaultInstance(props,    
         new javax.mail.Authenticator() {    
         protected PasswordAuthentication getPasswordAuthentication() {    
         return new PasswordAuthentication("[e-mail]","xxxxx");  
         }    
        });    
        //compose message    
        try {    
         MimeMessage message = new MimeMessage(session);    
         message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));    
         message.setSubject(sub);    
         message.setText(msg);    
         //send message  
         Transport.send(message);    
         System.out.println("message sent successfully");    
        }

catt（MessagingExc的e）{抛出新的Runtime异常（e）；}

调试：

 com.sun.mail.smtp.SMTPSendFailedException
    550 <narasimhatejav@teja> Sender Rejected - MAILFROM must be a valid domain. Ensure the mailfrom domain: "teja"  has a valid MX or A record.
    DEBUG SMTP: got response code 550, with response: 550 <narasimhatejav@teja> Sender Rejected - MAILFROM must be a valid domain. Ensure the mailfrom domain: "teja"  has a valid MX or A record.

但是如果我将主机更改为“smtp.gmail.com”，它就可以正常工作。

Answer 1

它是从本地主机发送的，因为您犯了大多数常见的JavaMail错误。

MAILFROM 问题是因为计算机上的主机名或名称服务配置错误。作为解决方法，您可以设置 mail.smtp.localhost 属性。

Answer 2

将Javamail Jar更改为v1.5，并添加javax.mail.internet.MimeMessage.set（字符串地址）函数
