We need an app that could verify emails existence;
1- Validate it is a proper email address
2- Get the domain of the email
3- Grab the DNS MX records for that domain
4- Create a TCP connection to the smtp server
5- Send a EHLO message
6- Send a MAIL FROM message
7- Send a RCPT TO message
8- If they all validate, return an object with success: true. If any stage fails, the callback object will have success: false.
After verifying a number of email using the process above, it should automatically change ip address.
We'll be using a server with multiple IPs.
It's very urgent.
