bulk email verification with ip rotation


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.
