secure php email form

[Dark_Matter]

I am currently using a script to allow users to send emails from my websites. Recently we started having problems with form hijacking...ie someone is using bots in an attempt to exploit security weaknesses in the script and send spam from our email server. More info here:Form email hijacking (http://www.anders.com/projects/sysadmin/formPostHijacking/)

I'm hoping someone can point me to a secure php email form that is not vulnerable to this attack. I would prefer free but I am willing to pay if necessary.

I know of dozens of free script sites...but are there any that rate the scripts according to security or that only provide secure scripts?

Thanks in advance, I have been lurking in this forum for a long time and have learned a lot.
