Mailengine with .NET API

I am looking for a mailengine that supports

Sending emails
Catching bounced emails
Support read confirmations
Show reports of mailing statistics (how many received/bounced)
Expose everything through an API that can be called using .Net

Does anyone know of any? It doesn't have to be free (always nice though) but it can't be a subscription. It has to be a one time purchase.

I tried Googling for them but I couldn't find one.

Solution

Well I'm aware of a couple of partial solutions, but not one big package:

Sending e-mails can be done via the normale .Net classes
Catching bounced emails can be done by reading the POP3 mailbox like http://www.codeproject.com/KB/IP/despop3client.aspx
Support read confirmations, can be done using a tracker image (see Newsletter: How is it possible to determine how many people opened the e-mail?). As far as I know is the Outlooks read confirmation system just a header that includes a callback e-mailaddress. You might be able to implement that with 2., not sure.
Show reports of mailing statistics (how many received/bounced), can easily be generated

You should be able to hack something together quite fast. There is no one big solution to do this, unless you want to buy a full newsletter system or something.
