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

abc@example.com

Is there a way to avoid this?

Thank you

    In short, you can't. Because even the domain exists, you can't guarantee the user/account does. – shinkou Oct 09 '12 at 07:49
  • You can try a MX lookup on the domain to see if that at least exists, but as shinkou said that doesn't guarantee the user account exists – Rainer.R Oct 09 '12 at 07:50

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."
