[Pkg-dspam-misc] crontab /etc/cron.daily/dspam

[Francisco Javier F. Serrador]

Hello

I'm using dspam backported by myself on sarge and I have found an error
on the script /etc/cron.daily/dspam: 

Where it says
if [ ! -z $DSPAMSTORAGE ]; then 

it should be:
 
if [ ! -z "$DSPAMSTORAGE" ]; then 

Also, DSPAMSTORAGE definition could be simply
DSPAMSTORAGE=`grep "^StorageDriver.*hash_drv.so" $DSPAMCONF`
