Function that discovers Email list from domain with validation

Hey I am George from ==> [login to view URL] ( feel free to subscribe to our early version!!! ) Our new product version needs a small task and we try to find the person who will work on this, as we do not have time for every task! Here is the task: 1. Given a domain ( for example [login to view URL] ) we need a script/function in python or node js ( or in any other language ) that will take this domain as an input 2. This function should return all the emails under this domain in an array: for example [john@[login to view URL] , maria@[login to view URL] , help@[login to view URL], .... ] 3. The function should validate that these emails exist preferably without sending an email to test it. If you see that this can't be done, you can try to do it with an email sent. 4. The whole point of this function is to discover all the email addresses under a domain. We need this function to our new product version, where we want an "automated email discovery process". Feel free to follow and write a message ==> only for questions <== on our twitter at: 1) [login to view URL] 2) [login to view URL] 3) [login to view URL] Thanks a lot, George
