[exim] starting exim upon boot with qq option

Hello,

I have edited the file exim.sh located in /usr/local/etc/rc.d/ to read

load_rc_config $name
: ${exim_enable="NO"}
: ${exim_flags="-bd -qq15m"}

Is it the correct file and place to edit so that my exim always starts
with qq15m option when machine boots?

Thank you for your advice!

Best regards from sunny Poland. BTW - We're playing Portugal today
(ouch... will hurt ;)
