PHP formmail getting spammed by bots



I'm getting spam almost daily now from bots crawling my site. Well it
seems they've learned how to work a form as well. I added $_POST for
the form but it seems that's not enough anymore. Any suggestions?
Blocking keywords for the bots won't help. I need a better alternative.

Thanks in advance!
