Logging to specific file

[Jason Rotunno]

Maybe someone can answer a simple question for me.  Right now dns 
activity is being written to /usr/adm/messages which is filling that file up 
quite a bit.  I'm trying to figure out how to log dns activity to a 
seperate file, say /usr/adm/dns or something.  I figure all I have to do 
is edit /etc/syslog.conf, but I'm not exactly sure what to put.  I've tried

named.*		/usr/adm/dns

and

domain.*	/usr/adm/dns

Neither of these worked, though.  Does anyone know how to have this 
logged to a serpate file?

Thanks.
