I'm going to try to get started on the initial install this evening to see what I'm dealing with. Things like "Can the email users adjust spam scoring rules or only the score that passes/fails?" If we have to manage the rules for all customers it adds a LOT of man-hours to our support queue. Spam is the primary reason we outsourced mail services. We're looking for a solution now that will allow the end-email-user himself to choose what is and what is not spam.
