完美解决 javax.mail.SendFailedException: 与 com.sun.mail.smtp.SMTPAddressFailedException: 抛错

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 aerchi@gmail.com

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: aerchi@gmail.com
     * 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>String[] mailTOArray=null;<span style="white-space:pre">		</span>
<span style="white-space:pre">			</span>mailTOArray=mailTOAddress.split(";");
<span style="white-space:pre">			</span>
<span style="white-space:pre">			</span>InternetAddress[] mailTOAdd = null;
<span style="white-space:pre">			</span>mailTOAdd = new InternetAddress[mailTOArray.length];
<span style="white-space:pre">			</span>for(int a=0;a<mailTOArray.length;a++)<span style="white-space:pre">	</span>
<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>}<span style="white-space:pre">	</span>
<span style="white-space:pre">			</span>
<span style="white-space:pre">			</span>msg.setRecipients(Message.RecipientType.TO, mailTOAdd);<span style="white-space:pre">			</span>
<span style="white-space:pre">			</span>
<span style="white-space:pre">			</span>msg.setSubject(mailSubject);<span style="white-space:pre">						</span>


<span style="white-space:pre">			</span>Multipart mailMulti = new MimeMultipart(); <span style="white-space:pre">	</span>
//<span style="white-space:pre">			</span>mailBody.setContent(mainText, "text/html;charset=utf-8");<span style="white-space:pre">					</span>
<span style="white-space:pre">			</span>mailMulti.addBodyPart(mailBody);<span style="white-space:pre">			</span>
<span style="white-space:pre">			</span>msg.setContent(mailMulti);<span style="white-space:pre">			</span>
<span style="white-space:pre">		</span>
<span style="white-space:pre">			</span>Transport.send(msg);    
<span style="white-space:pre">			</span>Out.println("...the mail send successful Second. "+Out.getNowDate());
    <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。
