Here is another way (just did this last night). This sends html mail also...
$headers = "Content-Type: text/html; charset=iso-8859-1\n";
$headers .= "cc: copy@server.net\n";
$headers .= "bcc: mail@server.com";
$to = "you@domain.com";
$subject = "The Subject";
$message = "The message";
mail($to, $subject, $message, $headers);
Bam!
