How to check if the mail has been sent successfully

Question

I am developing an Asp.Net application, where I am sending a mail to the user\'s email address, if he forgets the password.

I want to check if the mail has been sent

Answer 1

Put the .Send(msg) method in a try catch block, and catch SmtpFailedRecipientException.

try
{
    mail.Send(msg);
}
catch (SmtpFailedRecipientException ex)
{
    // ex.FailedRecipient and ex.GetBaseException() should give you enough info.
}
