Proxy / Port Listener - .NET

[Nyper]

I need to write (or find source for an already written) service that will listen on a specific port for incoming events. Basically, I need to write my own SMTP service. I'm just getting into this & just thought I'd post here to see if I could gain any quick leads..

Thanks ahead of time.

I was able to go through the SMTP RFC & a few other things & work out the basics of an SMTP conversation. I don't want to actually send the message with my program. I only want to grab it & pass it off to another program. So far I can accept a single message from a single user.. but I need to get it threaded somehow to accept many at a time, and I also have to work in authentication somehow.
