Hello,

I want to get where my email is sent or not. So that I set delivery notif.
I sent nonexistent email address to receive failed report but it raised an error.
Any ideas?

Thanks


Here is the code block :
mail.DeliveryNotification = EASendMail.DeliveryNotificationOptions.OnFailure Or EASendMail.DeliveryNotificationOptions.OnSuccess

Here is the error :

mail@domain.com : System.FormatException: Index (zero based) must be greater than or equal to zero and less than the size of the argument list.
