I am looking for a contractor to either create a web-based that will validate emails and install it to my server/website
The features I want will include
- ability to rotate IP addresses ( IP address has usernames)
- ability to upload lists of up to 50,000
- I want the output results to include valid, invalid, catchall, unknown.
It is required that it has the function to determine the difference between a valid email and a catchall email.
