How to get the mail sending stuff to work on Win2k?

I have a fresh install of PHP on a Win2k server. It is installed along with MySQL to allow me to run and XMB message base on my website. Everything works great except for the fact that I never receive any email notification when someone replies to a message I (or anyone else) posts. I think the problem is that I don't have the email part of PHP configured correctly. I used the php.ini-recommended file to set it up. In the mail section it says: SMTP=localhost There is a mail server on the local host. Do I have to install a sendmail app to get this working correctly? Nothing shows up in the event logs. One more question, when I make a change to that ini file, do I have to reboot the machine or just restart IIS? ================================ Rad Craig ================================ Rad Craig
