[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 [e-mail]

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: [e-mail]     * 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。
