How to Check if an Email Address Exists (without sending anything)

What in the world ru talking about?

Thank you, great video ^^

Is there a way to do something like this in PHP ?

I couldn't use telnet command on my mac, it shows command not found.

Can you make another explaining video about how to check bounce with this method for a emails list and also separate the bounce From the valids emails address

How to automate this process for large no of email ids

Is there any limit like 10 request per minute

"'dig' is not recognized as an internal or external command,
operable program or batch file." You must have installed Telnet somehow or enabled it. You should have covered how to do so in this video.

can we do it with python script??

Is there a way to find out who an email address is connected to without the email?

My ISP blocks port 25 , so i cant connect to the gmail smtp , any ideas on how can i solve or bypass that.?

do you know how kickbox or email verifcation service can do this in bulk? Because using this too much will only get ip blacklisted?

How do you have port 25 open? Is there a way without contacting the isp?

How can this be set to check multiple emails instead of one at a time?

does this work on any email or it just work for gmail?

it's getting stuck on"Trying <some ip>..."

How do I use it on windows?
