Hello

I don't know where can I do the setup for the email.

Normally PHP uses the installed email server (see: php.ini->sendmail_path) to send emails. That means PHP sends a call to the external email server if you use the function mail. In Windows the behaviour is a bit different (read about that fact in the linked manual site).

Is there a file need to be edit and setup for the email server?

Do you speak about a local installation of a web server (at home/work) and an installation of the forum in it? In this case you have to set up an email server to send emails or you have to instruct PHP to send the emails via an external email server (use your favorite search engine for howto's).

Tschö, Auge
