          for a swath of IP’s from Microsoft on a few different subnets?
          I’ve opened a ticket with Microsoft netops for it and I’ve
          done an rDNS bypass on our local antispam filter however we’re
          now seeing o365 clients with the same issue when trying to
          receive emails from anyone with an @outlook.com or @msn.com
          email address.. where do you draw the line in adding bypass
          after bypass?
