[乐意黎原创] 完美解决 javax.mail.SendFailedException: Invalid Address 与 SMTPAddressFailedException 抛错

       由于某个模块用到程序运行完后，自动收集结果发送邮件给相关人等。假如邮件收件人里某个地址貌似出问题，会导致所有的收件人地址都发送不出去。

抛出的错误如下：

javax.mail.SendFailedException: Invalid Addresses;
  nested exception is:
        com.sun.mail.smtp.SMTPAddressFailedException: 550 5.7.1 Unable to relay for [email protected]

这个是致使的错误呀，研究了半天。

改进代码如下：（跳过错误或不可达的收件人地址）

图A： 首次发送邮件。

图B： 捕获并输出不可达邮件，组装新的可达邮件。

图C： 二次发送邮件。

部分代码如下： 

                try{
	                Transport.send(msg);
//			Transport.sendMessage(msg);
			Out.println("the mail send successful First. "+Out.getNowDate());
		}catch(UnsupportedEncodingException e) { e.printStackTrace();
		}catch(SendFailedException  se) {	 
			 se.printStackTrace();
//			 Exception ex = me;
//			 if (ex instanceof SendFailedException) {}	
				 
				 Address[] unsend = se.getValidUnsentAddresses(); 
				 if(null!=unsend)
				 {	
//					 Out.println(" ==valid Addresses");
					 String validAddress = "";
					 for(int i=0;i<unsend.length;i++){
					     validAddress += unsend[i] + ";";
//					     Out.println((i+1)+": " + unsend[i]);
					 }
					 validAddress = validAddress.substring(0,validAddress.length()-1);
//					 Out.println("All: "+validAddress);
//					 send the mail when mail address wrong.
					 sendFailMail(new MimeMessage(mailSession), mailBody, mailFrom, validAddress);
				 }	 
			 
		 }catch(MessagingException me) {me.printStackTrace();}
	}
    
    /**
     * email: [email protected]
     * site: www.aerchi.com
     * blog: http://blog.csdn.net/aerchi	
     */
    //send the mail when mail address wrong.
    public static void sendFailMail(Message msg, BodyPart mailBody, Address mailFrom, String mailTOAddress )
    {
    	try{   
    		Out.println("...Send the mail second time.");
    		msg.setSentDate(new Date());
			
			msg.setFrom(mailFrom);			
			
			String[] mailTOArray=null;		
			mailTOArray=mailTOAddress.split(";");
			
			InternetAddress[] mailTOAdd = null;
			mailTOAdd = new InternetAddress[mailTOArray.length];
			for(int a=0;a<mailTOArray.length;a++)	
			{
//				Out.println(mailTOArray[a]);
				mailTOAdd[a]= new InternetAddress(mailTOArray[a]);				
			}	
			
			msg.setRecipients(Message.RecipientType.TO, mailTOAdd);			
			
			msg.setSubject(mailSubject);						

			Multipart mailMulti = new MimeMultipart(); 	
//			mailBody.setContent(mainText, "text/html;charset=utf-8");					
			mailMulti.addBodyPart(mailBody);			
			msg.setContent(mailMulti);			
		
			Transport.send(msg);    
			Out.println("...the mail send successful Second. "+Out.getNowDate());
    	}catch(MessagingException me) {me.printStackTrace();}    	
    }


	

最后，大功靠成。如有地址错误或不可到达（会自动跳过），保证能够对其它有效地址发送邮件，再也不用担心导致其它收件人不能收到邮件啦。
