PHP script with Gmail configuration

[utsav]

Hello There,

I have been trying to use the php mail script with gmail SMTP authentication using  IIS SMTP. But When I run the mail script, an error "fatal error class 'mail' not found in......"

However, it runs with my smartermail domain successfully!!!

Exactly what setting do I need  to configure to run PHP mail script with Gmail authentication.
