Mails with no data - only fieldnames

Hello,

I have a strange problem.
On my site: http://www.future-of-marketing.at I use chronoforms for two simple forms.
You finde them here:
http://www.future-of-marketing.at/seminare-webinare-ausbildung/social-power-20
http://www.future-of-marketing.at/kontakt-moeglichkeit

When I test them, everything is fine. I get the mail looking like this:

Name joachim
Telefon -
E-Mail [email]joachim.lackner@gmail.com[/email]

Nachricht/Frage

But sometimes (also today) I get mails looking like that:
Name {name}
Telefon {telefon}
E-Mail {mail}
Nachricht/Frage {nachricht}

Seems that chronoforms wasn't able to fill out the fields in the mail-template.
Thats very bad ... I don't unterstand how that is possible.

I hope you can help me.

Hi fomlackner ,

The most likely cause is spambots with JavaScript turned off. Add some very simple Serverside validation and you will probably kill most of them.
