    PMG huge blacklist blocks server

    Apparently a huge blacklist of 400k mail addresses and somewhat about 100k domains in the ruledb seems to slow down PMG server tremendously. I am speaking of delays from hours to days, not just minutes. I could not find anything in the documentation about limitations for the ruledb. @proxmox...
