You may not see the Email Message bit in Server Behaviors if you don't install DataBridge - Dreamweaver might not recognise the code as a server behavior unless the DataBridge files are installed. Please install this - it's now completely free. Just installing it won't affect anything else on your site until you actually want to use it and upload any files.
The new code I gave you in the previous post should work for you exactly as I've provided. You should also remove the old email code, which again is shown above.
Duplicate your contact page and call it contact2.php (I always do this before making any major code changes so that it doesn't affect the existing page). Add the new code and remove the old code as above.
Upload contact2.php and the new files I sent you, then open contact2.php in the browser and try sending an email. If it doesn't work, add the error reporting code to the top of the contact2.php page and try again, and let me know if there's an error message:
<?php
error_reporting(E_ALL);
ini_set('display_errors','on');
?>
