Robin,
While I love PHP this is one of those times it might pay to use perl along
with php. Contact pages and forms are gateways to all kinds of problems.
"nms formmail" works great and is fairly secure.( Just don't emulate matts
formmail or turn off the security features.
To protect your self from the scriptkiddies rename your scripts and files
and modify your code to match. How do I know these things? Being black
listed is no picnic to overcome.
God bless,
al
