Could not execute: /var/qmail/bin/sendmail

Hi, I get this error with my basic form (Could not execute: /var/qmail/bin/sendmail) when I submit it in the frontend.
Does anyone know what I did wrong?

I have Joomla 1.7.2 and chrononforms v4

Thanks in advanced
greetings,
Aaron

Hi Aaron,

It sounds like sendmail isn't set up or isn't configured correctly on your site.

Hi Bob, thanks for your reply.

I thought so to, but I can't really figure out what is wrong.
Have the problem also with smtp and php mail (php mail = Could not instantiate mail function)

I did not have this problems with any other site I have build so I don't really know where to look.

greetings,
Aaron

Hi Aaron,

I can only suggest that you check with your web host what settings are required.
