Is there a way to tweak the spamassasin settings besides the few in ispconfig? How about having the spam sent to a quarintine instead of being delivered to the user inbox, and then have a spam digest sent??
You can either modify one of the config templates in /root/ispconfig/isp/conf/ or you modify the global spamassassin config in /home/admispconfig/ispconfig/tools/spamassassin/
