I am sending mail using

System.Net.Mail;

. I want to catch exception in case of Recipients email id invalid or not available. I my code "SmtpFailedRecipientsException" is not throwing exception in any case.
What is exact use of

. How can I identify that "ToEmail" is invalid/not available. Please help.

What I have tried:

using(Smtp client = new SmtpClient())
{
try{
client.Send(message);
}
catch(SmtpFailedRecipientsException ex)
throw ex;
}

You can't tell if it's not valid. If it's in the wrong format then it will throw an exception when you add it as a recipient, but if the email address is in the right format but not a valid recipient then it's impossible to know at that point in the code. Some of this does depend a little on the target smtp server, but in general you can't know if an email address is valid.

Can we pull sender's inbox to identify which mail delivery has failed?

Yes, that's a common way to deal with this.

ok. Thanks. I googled around that.Got solution as use pop3client. I dont knw about it. Can u share something about this. Which dll is to usee for this.

There's no built-in .net classes that can use pop3 so you're going to have to google for one someone else has written and pick one you like (edit: or learn pop3 and write your own :) )
