Client accessable mail server system

In this sytem there are "clients" (my clients) and "customers" (my clients' potential customers). A "customer" views a "client's"? advertisement on some media; print, TV, radio, whatever. Contained in this advertisement is a coded email address... maybe <offer1@[login to view URL]> at one location and? <offer3@[login to view URL]> ? for another. Whatever it takes to track the source of their information. The customer respondes by sending an email to this address. When? the email arrives at my system, the "customer's" ? information is stored in a MySql DB, and an auto-responder sends a coupon or other offer? to the "customer" specific to the incoming coded email address. At any time the "client" can log in and access their auto-responder area and change their coupon or other offering.? The response email? can be either text or graphics based.? I would not expect a graphics editor to be part of the package.? The "client" would have to upload graphics. This must be scalable for a large number of clients and auto-responder offers. ## Deliverables I feel I said eveything in my original post: In this sytem there are "clients" (my clients) and "customers" (my clients' potential customers).
