I’m not even sure how they’re getting the bounces from Outlook, as most are handled inline. > This sounds to me like your customer is using a really bottom of the > barrel spamto: list (on par with our bait list, to be found at > https://www.bsdly.net/~peter/traplist.shtml, which serves a > slightly different purpose).
