You can use: 1. A honey pot field (a field hidden by CSS, with an indicator to "leave this field blank"); if it's filled it's probably a bot, so don't process... or 2. CFCAPTCHA to generate a captcha and make the user type what's shown; send only if it's a match... or 3. CFFORMPROTECT - http://cfformprotect.riaforge.org/
These are pretty much listed in order of the least effort first. They all work to varying degrees, but I've found just the honey pot will knock out most of it.
