[PJUG Javamail] Captcha and Simple web form submission

[Vijay Balakrishnan]

Hi,

I have a simple web form with 5 input boxes and when it is submitted, an
email is sent to the receiver.
Now, we get a ton of spam from these forms.

Captcha(Yahoo) was recommended as a solution but it is very intrusive and
forces the user to enter an input textfield that has nothing to do with
their business purpose.
Has anyone done any other solutions ?

TIA,
Vijay
