How to check if an email address exists without sending an email?

I am trying to find some way to test if an E-mail address actually exists without sending a test mail.

One can validate e-mail address but is not guaranteed if the address actually exists. like

[email protected]

Is there a way to avoid this?

Thank you

Short answer is no - the only way to validate it exists is to connect to the mail server and send an email to it.

"SMTP defines a command for this, but since abuse by spammers totally overwhelmed the number of legitimate uses, virtually every e-mail server in the world is configured to lie."
