Discovery Accelerator Email Filter

Presently in DA when you do a search for email to a specific user you not only get the relevant email but you also get non business email like on-line newsletters, email broadcasts, system notifications and so on. Wading through mountains of system notifications, change notifications and all this garbage that is required within the business but not relevant to a legal search is a waste of time

It would be nice if it was possible to filter out these emails from the search results. Would it be possible to have something like the filter on the SPAM filters where you can select categories to exclude (and the option to do updates to these categories via a weekly download from Symantec, maybe even tie it into the Symantec SPAM filters) and then have a custom one where you can specify the internal generated emails you want to filter that way it will greatly decrease the results in the search and make the results more efficient than at present
