Below code is workin fine . However I need get Failure or Success Notification to Specific address (b@technospine.com). But I'm receiving Delivery Notification mail to FromMail address(A@technospine.com). Can you please help me to resolve this problem?
SmtpClient smtpClient = new SmtpClient();
MailMessage message = new MailMessage();
MailAddress fromAddress = new MailAddress("A@technospine.com", "BALA");
MailAddress adminAddress = new MailAddress("b@technospine.com");
smtpClient.Host = "Mail Server Name";
smtpClient.Port = 25;
smtpClient.UseDefaultCredentials = true;
message.From = fromAddress;
message.To.Add(_sendTo); //Recipent email
message.Subject = _subject;
message.Body = _details;
message.IsBodyHtml = true;
message.Headers.Add("Disposition-Notification-To", "b@technospine.com");
message.DeliveryNotificationOptions = DeliveryNotificationOptions.OnSuccess;
message.ReplyTo = adminAddress;
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpClient.Send(message);
