Hi.
I've noticed some issues with the postgrey init script.

Most notably, it attempts to write /run/postgrey.pid as the user running postgrey. My /run doesn't have world-write permissions, so this fails, and the PID file is never written. As a result, it is not possible to stop or restart postgrey using the init script. Moving the pid file to /run/postgrey/postgrey.pid, and creating /run/postgrey with correct ownership in the init script works well. For example:

----------
PIDFILE=/var/run/postgrey/postgrey.pid

[[ -d /var/run/postgrey ]] || mkdir -p /var/run/postgrey
chown postgrey:postgrey /var/run/postgrey

PID=`cat $PIDFILE 2>/dev/null`
[ -d /proc/$PID ] || PID=""
----------

A second issue is that I can't get quoting to work right when the --greylist-text= option is set in $POSTGREY_OPTS inside /etc/conf.d/postgrey. I haven't had success setting a message that contains spaces, and have tried much escaping of quotes and spaces. Surely there's a means of making this work. If so, I'd like to know how, and this should be indicated in the comments of the configuration file.

I know Gentoo had similar issues with quoting. They solved it by using a $POSTGREY_TEXT variable to the config file, and using it directly in the init script. This works well for me:

------
[ -z "$PID" ] && $POSTGREY_BIN --daemonize --$POSTGREY_ADDR \
--group=$GROUP --user=$USER $POSTGREY_OPTS --pidfile=$PIDFILE \
--greylist-text="$POSTGREY_TEXT" > /dev/null
------

Thanks.
