Hi all,
I’ve been hearing more and more about form mailer scripts being “stuffed” by spam bots. These programs search out form mailers. Then, by adding specially-formatted strings to the various fields, they force the mailer to send out spam messages.
I have written a mailer script that should be resistant to most programmatic attempts at such attacks. If you’re interested in giving it a try, check it out at:

It’s a very configurable script that you can use to handle a contact us type form or a tell-a-friend type form. You have some control over error handling and what happens post-mailing.
I’ve tested it out with some simple use but I haven’t put it service on a production site yet. So, give the tires a really good kick before you put this onto your live site.
