[Exim] Logging all emails etc etc

Greetings,

I'm setting up EXIM as SMTP and Qpopper for POP.
They are Working FINE !

But I need help, I'm trying to redirect the log into syslog using
log_file_path=syslog
It does not work.. Everything keep going into
/usr/exim/spool/log/mainlog
Does anybody have an Idea?

The second thing i want to do is having a File or something that give me
Statistics of my Server.
How many email was sent each Day, each week etc etc.
I tryed exmstats but it does "nothing".. Maybe there is something i
don't understand.. I've read the docs and Faq.. But failed to
understand. Can somebody help me ?
