When running a PHP script from cron, you must run it through the php binary. When you view a PHP script in your web browser, the web server hosting the PHP file does that for you automagically.
So to run your cron job, do something like this:
00 01 * * * /path/to/php /home/www/web(number)/web/auto/mail.php
Hope that helps!
