Recommend Extensible SMTP Server

Question

I have such a strange situation when I have to accept email from my users. I want to be able to intercept an incoming SMTP message, see if it is checked (check the username and password and check against my user database), then completely parse the message and do something (register the message in my application, for example). I need someone to do a hard climb for me and take care of the SMTP protocol, transport encryption, etc., and let me take care of the rest.

My problem is that I can’t find an extensible SMTP server that either allows me to connect to its processing pipeline or embed it in my application or service. You know him? I would like to program the SMTP logic in C #, but I can consider other parameters, such as external handset programs, COM objects running on a Unix system under Mono, etc.

The Neokernel Web Server package includes an SMTP package that can meet your needs.
