i've got a problem with the "message command "option
here is my config in smb.conf
message command = /usr/local/samba/var/popup/get_popup "%f" "%t" "%s" "%I" &

and the get_popup script

date=`date +%d-%m-%Y`
heure=`date +%H:%M`
message=`cat $3`
infos=`/usr/local/samba/bin/nmblookup -A $ip | grep "<03>"`

echo Le $date a $heure la machine $machine a envoye le message suivant : >>
echo $message >> /usr/local/samba/var/popup/popup.txt
echo a destination de $destinataire >> /usr/local/samba/var/popup/popup.txt
echo $infos >> /usr/local/samba/var/popup/popup.txt
echo "************************************************** ***************" >>

when i send a message only to the server i can get the message and all the information in popup.txt,
but when i send a message to all the domain it doesnt works
is somebody got an explication

thank you and sorry for my poor englis
