The .Net SmtpClient's Send method returns void. It only throws two exceptions, SmtpException and a FailureToSendToRecipientsException (or something like that).

When using SES, for successful email delivery SES sends back a 200 OK message with the message id. This message id needs to be tracked.

How do I do this using the C# SMTP api?

Edit: The SMTP protocol mentions various response codes sent by the SMTP server. I am looking for a SMTP library that exposes the "final" response code to the caller. I am already aware of the SES HTTP API. I am not looking to use that for the moment.

c# amazon-web-services smtp amazon-ses
