Good point, but notice that cmeclax said in his example procmail recipe:
It should be possible to pick a header that a spammer is not likely forge. He was
even careful not to reveal in public just what header(s) he is checking.

Could anyone who is interested clarify this for me.
Or point me in the direction of a site that does GPL case studies where there may be a similar issue. I have had a google around and the PHP site wasn't help full and the GPL page didn't seem to have this senario.
The setup is as follows:
I develop a piece of code using PHP 3.0.9 which is, to
my knowledge, GPL.
The piece of code runs on my server and is an integral part of a system that I have developed for a client. I did not recieve  payment for this particular piece of code but I did recieve payment for the system. My client now wants to
use a different service provider but keep my code.
Do I have a right to claim intellectual property rights for  my little piece of code that he did not pay me for or do I have to give the client the code under the GPL.
I know this is not strictly a 'Linux' issue but any help would be appreciated
