Can I get banned for pinging email adresses?

I need to check a list of about 40 000 mails if they are valid. I want to use this guide: http://www.labnol.org/software/verify-email-address/18220/ It works perfectly one by one but I am afraid that if I made a program that would check them all I could get banned mainly because it would be basically a dos attack.

What do you think? |Is there another way? I cant use any online service for that as I dont own the list of emails. Thanks

Solution

  • I cant tell you if you will get banned but the techniques I would use to avoid getting banned are

    • Use a public IP address, proxy or vpn (eg mobile internet, wifi hotspot, TOR) as if you do get banned it wont effect you
    • start slow, process 5-10/s at first and then speed up, if you get blocked by one server go back to your last known good speed and don't connect to the blocked server for a while, check if you are still blocked manually
    • depending on the connection setup speed, only do a few emails per domain at a time. ie do 1 @gmail.com, 1 @Hotmail.com and 1 @yahoo.com per batch this stops you flooding one email server with thousands of requests at a time.

    Hope this helps
