    If you have a paid hosting site, then log into your Control Panel and look for the Domain Blocking utility. Just enter the IP address and it will write to the .htaccess file for you. Couldn’t be easier.

    If I understand you correctly, people are creating a html form on their website that submits to your processing script to send the email.

    If so, add a check such as

    if($_SERVER['HTTP_HOST'] == "yourdomain.com")
    // execute script
    else
    // print error saying they can’t submit from another domain

    You can also try dynamic html field name variables.. ie. when the html form loads, generate.. say… a 10 character name for the field, save it to a session, and when it submits load the session variables for the appropriate fields. This will prevent them from being able to submit from any form other then the one you have on your website (this is usefully as well in preventing certain type of form hijacking used to send spam email).
