[Formit] Could not instantiate the function mail()

Dear All

Someone has experience with formit?

I just installed it with Catcha.
While I filled up the fileds and send it, I got that error message

An error occurred while trying to send the email. Could not instantiate mail function.

It's a bit funny because if I use the function mail() in a snipet, it works.

Some one has a idea how I can configure Formit or SMTP section?

Thanks cheers

Please don't double post.

Sorry. I wanted to delete after I saw a forum for FORMIT
