You can't send messages via IMAP, you can only send them via SMTP.

Sending messages via SMTP do not put them into any IMAP folder. You have to put them there yourself.

That's not a feature that IMAP supports.

What you want is SMTP delivery status notifications: mimekit.net/docs/html/…

Not all SMTP servers support this feature, however, so there is no guarantee that you will actually receive them. Then, once you receive a status notification which will come as an email with a Content-Type of multipart/report with a child part of message/delivery-status: mimekit.net/docs/html/T_MimeKit_MessageDeliveryStatus.htm
