It sounds like you have a PHP script with a security vulnerability, and
you think that restricting what the client uses to request the script is
going to fix it. This is not a good approach. Just fix the problem. :-)
For example, filter the data you receive from the client before passing
it as arguments to the mail() function.
Hope that helps.
