Email Error: Could not instantiate mail function

[Kami123]

Hello,

My friend accessed my Zen Cart store.

(http://wp1151878.wp022.webpack.hosteurope.de/index.php)

When he's asked to enter his address, email and his (new)

password, here's the the error message he gets:

" Email Error: Could not instantiate mail function.
Please check Admin->Configuration->Email Options->Email Transport."

I am using a linux/unix server, I am not sure what option I should select as the Email Transport.

Thanks in advance for your help,

Kami
