Hunts look good. Waiting to see if I can get more mode results before tagging it for review.

nice telem on this! any reason not to just use freemail provider list? it doesn't seem to change the results much in hunting with it, but just gmail seems highly specific. would need to change file name, rule name and description if you decide to go with it
