Enable Statistics Logging

Hi All,

I have a small mail server running on a Mac G5 desktop OS X 10.4.9,  
using postfix 2.1.5 and qpopper 4.0.9. I am trying to enable  
statistics logging and haven't had any luck. The earlier versions of  
OS X worked off of an inetd.conf file where I put in;
#pop3   stream  tcp     nowait  root    /usr/libexec/ 
tcpd               /usr/libexec/popper qpopper -s
But the newer OS uses xinetd and I'm not sure how to enable the  
logging. Can someone please put me on the right path.

Thanks Much,
Jim
