I want someone to write me a system to do the same as [url removed, login to view] opt-inbox
We want the system to do spam email filtering via email challenge response.
Have a look at [url removed, login to view] opt-inbox so you know what we are after.
The system allows a user to have their emails checked on if they are not on a whitelist it will send the sender an email to verify they are human. This then sends the email on to them and puts them on the whitelist.
We require the source code and the system fully working before payment is made.
You first bid is your final bid, don't ask for more money if you win.
