use the mail() function.
To send to two addresses, set your headers
$to = "visitor@yoursite.com";
$msg = "test";
$subject = "test email";
$headers = "From [email]admin@yoursite.com[/email]\r\n";
$headers .= "Cc: [email]address2@domain.com[/email]\r\n";
mail($to, $subject, $msg, $headers);
EDIT: Sorry sijis. Didn't know anyone had responded. I had a reply an hour ago and forgot to submit. When I realized the window was open, I subitted. 😉
