Delphi 7 SPAM Filter Upgrades

I have a SPAM Filter that I want to add a feature to the program. I need a company that is very good working with Delphi 7. The program is functional now but I want to add a feature where the sender gets an email back if they are not on the intended recipients approved list. The sender will answer a question and then the email goes through to the intended recipient. When the sender puts in the correct answer they get a message that it is correct and they will also see other products that we offer. This feature is similar to what Spam Arrest does. I will need to send you the source code of what we have done already. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
