We need a script/system to verify emails in bulk. There are plenty of scripts available online but we are facing some troubles using those script as follows
1) Using those script, we may get our IP blacklisted as we need to use our SMTP to verify emails, and verifying emails in huge quantity will definitely block our IPs fast. So need a system that can verify without our SMTP.
2) We are not getting proper results for yahoo, AOL, Outlook, etc. Sometimes it gives valid and sometimes unknown...
3) Slow verification.
So we need the following things
1) The script should verify emails with at least 97% of accuracy.
2) It should verify Yahoo, AOL, Hotmail, Outlook, etc accurately
3) Speed should be high in the verification.
4) We just need a proper script with logs without any GUI or anything else. We will integrate with our current system.
