[sniffer] It's worth it

So, I've been using the "free trial edition" of Sniffer for the better part of 2 years (wow, time flies!) and just purchased two licences.   On a message volume of 18,000 messages (14,000 spam) I used to see the "free trial edition" trigger on 2,000 with very low false positives.  Now, it's more like 13,000 with no change in the false positives.   Thanks, SortMonster!
