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

You can use the DeliveryNotificationOptions to receive a receipt.

If you have a MailMessage object named mail, do this:

mail.DeliveryNotificationOptions = DeliveryNotificationOptions.OnSuccess;

Answer 2

If you're using System.Net.Mail try out

message.DeliveryNotificationOptions = System.Net.Mail.DeliveryNotificationOptions.OnSuccess;

Answer 3

if your SmtpMail.Send(message) method returns no error, it means the email was sent to the SMTP server, then you are out of your jurisdiction, that is how far you can know.

Answer 4

I'am using gmail SMTP for sending mails with my program. A fake mail sent returns Ok even with SmtpFailedRecipientException trap.

But when I check with outlook my gmail recipient I see that mail was not sent with explanation. With a subject Delivery Status Notification (Failure)

My question is it possible to get this notificiation whitin the program.

I found this but it's not for POP

Notify C# Client, when SMTP Server receive a new Email

Answer 5

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.
}

Answer 6

The SmtpClient.Send method will raise an Exception if there's a problem sending. But beyond getting that message to the SMTP server, there's no way to know if it makes it to the destination from there.
