[exim] PS Change Exim's log_file_path (it's not working)

PS: Luckily I read the syslog and it said that access to main.log was
denied. Well seeing it didn't exist yet I created it and set the correct
owner and rights. Now it logs deliveries there just fine. BUT it stopped
logging in the syslog even though I changed it to log_file_path =
:/somepath//%s.log so it would use the built-in log path too.
