Java邮件API例外

Question

我试图从Web应用程序发送邮件时，此异常：

com.sun.mail.smtp.SMTPSendFailedException: 550 5.7.1 Missing 
or literal domains not allowed 

我使用类似下面的代码性能。

Properties props = new Properties(); 
props.setProperty("mail.transport.protocol", "smtp"); 
props.setProperty("mail.host", "smtp.verizon.net"); 
props.put("mail.smtp.auth", "true"); 
props.put("mail.smtp.port", "465"); 

我还使用身份验证方法使用用户名和密码对用户进行身份验证。

只有当我通过身份验证时，我才得到成功消息。当我去到名为transport.sen(message)的行时，我得到了异常。

this is my full code.. 



try { 

      MimeMessage message = new MimeMessage(session); 
      message.setFrom(new InternetAddress(from)); 
      message.addRecipient(Message.RecipientType.TO, new InternetAddress(
        to)); 
//   message.addRecipient(Message.RecipientType.CC, new InternetAddress(
//     cc)); 
//   message.addRecipient(Message.RecipientType.BCC, 
//     new InternetAddress(bcc)); 
      message.setSubject("TEST...!!!!!!!"); 

      Multipart multipart = new MimeMultipart(); 

      BodyPart messageBodyPart = new MimeBodyPart(); 
      messageBodyPart 
      .setText("Dear Sir, Mail Testing"); 
      multipart.addBodyPart(messageBodyPart); 


      messageBodyPart.setText("Hao test"); 
      message.setText("Kader here"); 
      message.setContent(multipart); 


      MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap(); 
       mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html"); 
       mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml"); 
       mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain"); 
       mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed"); 
       mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822"); 
       CommandMap.setDefaultCommandMap(mc); 
      Transport transport = session.getTransport(); 

      transport.connect(); 
      Transport.send(message); 
      transport.close(); 


      System.out.println("Sent message successfully...."); 
     } catch (MessagingException mex) { 
      mex.printStackTrace(); 
     } 

Answer 1

有一些邮件服务器有可能在客户端日志记录时自动将域名追加到用户名上，但是某些服务器不会登录，从而导致认证失败。

Try this code :- 

MailUtil.java 
------------ 
package com.test;

    public boolean sendMail(String[] recipients, String[] bccRecipients, String subject, 

    String message) {

     } 
     msg.setRecipients(Message.RecipientType.TO, toAddresses);

     Logger.getLogger(MailUtil.class.getName()).log(Level.SEVERE, null, ex); 
     return false; 

    } catch (MessagingException ex) {

    } 
} 

class SocialAuth extends Authenticator { 


    protected PasswordAuthentication getPasswordAuthentication() { 

     return new PasswordAuthentication(FROM_ADDRESS, PASSWORD); 

    } 
    } 
    } 

Main.java 
---------------- 
package com.test; 


public class Main { 

    public static void main(String[] args) { 
    String[] recipients = new String[]{"example1@gmail.com"}; //To

    subject, messageBody)); 

    } 
    }
