Mail Delivery Check on the Server

I want to have a Server-Side Software (can be an extension to Joomla), that checks the Delivery of eMails and the sorting-out by spam-filters. A User should get a special eMail-adress, where he can sent an eMail to. Then he sents an eMail to that eMail-adress, and the server checks most of the spam-filters like: - Spamassasin - Spamfighter - Norton - Zonelabs After that the user should get a little statistic, that shows him, how much and which spam-filters sorted the mail as spam. For me this is a service-project, so I don´t want to integrate everything, it is depending on the price. I know about three kind of spam-filters: - server-sidet - client-sidet - AOL, GMX,... The software should also check if the mail-server is blacklisted somewhere. This service is someghing like light-version of [[login to view URL]][1], but it also should keep free, so there is not the need for to be as extendet as deliverywatch. I have no clue about the pricing of that project, and I don´t know if I would do it when it is getting to expensive. So just give me? a hint about the price, how you would like to set it on and then we look if we go deeper into that, okay? ? ? ? ? ? ? ? ? ? ? ?
