try:
foreach ($arr as $key => $value) {
    echo "Key: $key; Value: $value<br>\
";
}

before your foreach:
unset ($HTTP_POST_VARS['submit']);
this will pull it out of the array

change the foreach statement above to:
foreach ($arr as $key => $value) {
    echo "Key: $key; Value: $value<br>\
";
    $message .= "Key: $key; Value: $value<br>\
";
}

and then use the mail function, something like:
mail($contactemail, $subject, $message, $headers);
to send the values.
