When I want run exim service (after apk add exim , configure exim.conf and add service default)

mail:/etc# rc-service -v exim status
* status: stopped
mail:/etc# rc-service -v exim start
* checkpath: owner `-m’ not found
* checkpath: owner `-m’ not found
* ERROR: clamd failed to start [ !! ]
* ERROR: exim failed to start

On the exim service script

/etc/init.d/exim service script has
[..]
command_args=${command_args:—bd -q15m}
[..]

but Exim documentation http://www.exim.org/exim-html-current/doc/html/spec\_html/ch-the\_exim\_command\_line.html
specify
[..]
-bd
[..]

with only one “-”

Is there an error in exim script ?

Thanks
