coppermine doesn't have it's own smtp engine (which sends email), but has to rely on the smtp engine that has to be set up on your server. Most Lunix servers come with smtp properly set up, but IIS doesn't.
Since you're using IIS, you'll have to set up / configure your smtp server first. If you're sure that smtp server is set up correctly on your webserver, you might have to enter the correct data into include/mailer.inc.php:$CONFIG['smtp_host'] = '';
$CONFIG['smtp_username'] = '';
$CONFIG['smtp_password'] = '';
(but remember: you'll have to get smtp to work in the first place!).

P.S. Bottomline is: do not run your own server publicly unless your really know what you're doing... :wink:
