contact form sending spam?

contact form sending spam?

I just setup a site with the contact form a few days ago, and this morning woke up to over 100K spam that are in the mail queue that have come from my server. There isn't a X-php header to ID the site, but the form solution is the only php script I've added in some time.

Has anyone had an instance of the form being exploited?

Are there any extra security measures that can be used?

The Contact form included with the solution pack has three security measures in place.

1) Honey Pots - These are two hidden form elements that are validated to ensure that they are blank. The idea is that if a Robot is hijacking the form, they will will fill in all of the form elements including the hidden ones. If this happens, the form will fail validation.

2) Security Question - This is a question that only a human filling the form would be able to answer correctly

3) Captcha - Similar to the security question, this is an image that shows random alpha numeric characters that only a human would be able to read and enter correctly.

It is possible that a person is manually exploiting your form, but there isn't a lot that can be about that. you could ban access based on the IP address, but that doesn't work if the IP changes.
