Autorespnder (Dot Net)

I need a autorespnder coded for mailing we are basically looking for a tool that does just that. .net platform would be great, either C# or vb.net We would want it to be broken down by smtp and pop server For Example. I would create a new "campaign" in this program. I would specify the pop3 and smtp server then I would load in a list of pop3 accounts that it will check at changeable intervals. we would also setup a message that we can use tokens with, for example {hi|hello|good day} I would also like a step system. so the first time the program reads an email from the pop3 account. it will send the first message. when the next email is recieved it will send message 2 is what I currently use ashish we want a more streamlined version of this [login to view URL] to see it in action we obviously want something better or we'd use that basically we need something muc hmore scalable that one starts to freeze up wi higher volume, we want something that performs at 1 lead the same it would at 100k leads (emails that come in to be responded to ) how tat one works is it logs into a pop email account (gmail, your own domain , wahtever) and downloads all new unread messages in the inbox, and puts them in que to be responded to based on paramaters for the campaign and removes it from the pop inbox to avoid responding to that email twice ## Deliverables
