I am thinking of writing a utility, but want to see if there is one out there already that does this, so i dont waste any time. Here is what I am looking to do: Sort of like an autoresponder, except it is triggered by an incoming email. For example, Joe Shmo responds to an ad via email. as soon as my software receives the email from Joe Shmo, it will send joe shmo an email back with a generic email back a certain time later (this email back to him will look like a real message and not an auto response). then joe shmo responds again responding to the mail i sent him, and when i recieve email #2 from joe, my software knows it is the second time joe sent me a email, so it sends him a different generic email. the point is joe thinks he is having a conversation with someone, but it is a generated message system. does this exist already? if so what is it called, if not, maybe i will have to make it. would anyone else find this useful as well?
