Topic: Sending mail from .NET application
I am trying to send emails via Dynu SMTP Relay from a .NET application.
See below for the code I am using for sending mail.
MailMessage message = new MailMessage(SENDER_ADDRESS, gsEmailAddress);
message.Body = "text";
message.Subject = "subject";
SmtpClient smtp = new SmtpClient("relay.dynu.com");
smtp.Credentials = new System.Net.NetworkCredential(SMTP_username, SMTP_password);
try {
smtp.Send(message);
} catch (Exception ex) {
}
When I execute the code, I receive the error message “SMTP authentication is required”.
Is there anything I am missing?
Is it not possible to use SMTP Outbound Relay from our own application?

I tried with smtp.dynu.com, but received the same error message.

Shouldn't smtp.dynu.com be used instead?
