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。
邮件里有个地址貌似出问题，导致所有的收件人都发送不出去。
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]

图示： 抛错
这个是致使的错误呀，研究了半天。
改进代码如下：
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
<span style="white-space:pre"> </span>try{
<span style="white-space:pre"> </span>Transport.send(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.
<span style="white-space:pre"> </span> //调用再次发送代码
sendFailMail(new MimeMessage(mailSession), mailBody, mailFrom, validAddress);
}
}catch(MessagingException me) {me.printStackTrace();}

补调用代码：
/**
* email: [email protected]
* site: www.aerchi.com
* blog: http://blog.csdn.net/aerchi<span style="white-space:pre"> </span>
*/
//send the mail when mail address wrong.
public static void sendFailMail(Message msg, BodyPart mailBody, Address mailFrom, String mailTOAddress )
{
<span style="white-space:pre"> </span>try{
<span style="white-space:pre"> </span>Out.println("...Send the mail second time.");
<span style="white-space:pre"> </span>msg.setSentDate(new Date());
<span style="white-space:pre"> </span>
<span style="white-space:pre"> </span>msg.setFrom(mailFrom);<span style="white-space:pre"> </span>

<span style="white-space:pre"> </span>
<span style="white-space:pre"> </span>InternetAddress[] mailTOAdd = null;

<span style="white-space:pre"> </span>{
//<span style="white-space:pre"> </span>Out.println(mailTOArray[a]);
<span style="white-space:pre"> </span>mailTOAdd[a]= new InternetAddress(mailTOArray[a]);<span style="white-space:pre"> </span>

<span style="white-space:pre"> </span>}catch(MessagingException me) {me.printStackTrace();} <span style="white-space:pre"> </span>
}
最后，大功靠成。如有地址不到到达，再也不用担心导致其它收件人不能收到邮件啦。
