Perfect solution to Javax.mail.SendFailedException: with com.sun.mail.smtp.SMTPAddressFailedException: Throw the wrong

Since a module is used to run the program, automatically collect the results to send messages to the relevant people.

There is an address in the message that looks like a problem, causing all the recipients to send out.

The following errors are thrown:

Javax.mail.SendFailedException:Invalid Addresses;
Nested exception is:

Illustration: Wrong throw

This is the cause of the mistake Ah, studied for half a day.

The improvement code is as follows:

Figure A: Sending the message for the first time.

Figure B: Capturing and outputting unreachable messages, assembling new unreachable messages.

Figure C: Send the message two times.

Some of the code below

<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>//Call again to send code sendfailmail (new MimeMessage (mailsession), Mailbody, Mailfrom, validaddress); }}catch (Messagingexception me) {me.printstacktrace ();} ----------------------------------------------------------------------------Fill Call code: /**     * Email: [email protected] * site:www . aerchi.com * Blog:http://blog.csdn.net/aerchi<span style= "White-space:pre" ></span>      */   //send The mail address wrong.    public static void Sendfailmail (Message msg, Bodypar T mailbody, Address Mailfrom, String mailtoaddress)     {    <span style= "White-space:pre" >< /span>try{      <span style= "White-space:pre" ></span>out.println ("...

Finally, the merit depends. If you have an address that doesn't arrive, don't worry about causing other recipients to receive the email.

This version of all, reproduced please specify the original address.
