    It has been asked many times before in comp.lang.php use the archives.

    But in short, the only way to really verify is to send a challenge to
    the address that could be solved by a program. The text hidden in images
    solution comes to mind...

      Without sending an email, you can check it's syntactically correct, and that's
      about it. This is Asked Frequently.




      If you want to make sure a human is reading it, send an email containing a URL
      to a page on your site with a unique identifier, and ask the person to visit
      the URL. You'd have saved the ID when sending the email, then later if the URL
      is visited, you can mark that email address as "verified".

        [FAQ] Check validity of email address (Was Re: verify email address)

        Q: How can I check the validity of the email address?
        A:
        1. Use regular expressions to check the format/syntax of email
        address.
        2. Use SMTP's VRFY or EXPN command. Note, many turn off this command
        for spam abuse.
        3. Use checkdnsrr() or getmxrr() to see if the domain has MX records;
        and then check if the domain exists.
        4. Send a real email to the user, but with an activation URL.

        Caveats:
        (1) can check only the format and doesn't check if the domain exists or
        not
        (3) checks only the domain
        (4) is the only (right) approach to see if the user uses is own-valid
        email address.

        Refer:

        Check DNS records corresponding to a given Internet host name or IP address

        Get MX records corresponding to a given Internet host name
