[exim] Exim FreeBSD queue separate runnes

Hello.

May be wrong list...

I found in Debian Exim option to make a separete queue runner in
/etc/default/exim4
It is looks like this:

/usr/sbin/exim4 -bd
/usr/sbin/exim4 -oP /var/run/exim4/eximqr.pid -q5m

How make this in FreeBSD? RC script seems to don`t know anything about
this.
