[Dovecot] dbox

Hi Evaggelos,

I had the same issue and I solved it with a little bash script. The 
trick is to use the xargs function to break up the spam list in smaller 
blocks (I also restrict spam processing to spam older than $TIME_LIMIT 
in order to let time to user remove non-spam, and ignore filename ending 
with T as they have already been removed). Relevant lines :

find ./ -iname "*" -mtime +$TIME_LIMIT -print | grep -v T\$ > 
$TEMP_FILE_NAME
cat $TEMP_FILE_NAME | xargs -r -n500 sa-learn --showdots --spam -C 
$SA_CONF_DIR

Cheers,

Denis
