In the "Forgot Password", as sa to edit your email administrator to send the password to the members?
I'm using JohnCMS4, but when using this function it says competition is "Error sending E-mail" to notice:
Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\AppServ\www\jcms\users\skl.php on line 70
