We see similar issues with smartscreen. We tried to understand this since the past june, but we only got automated answers or real people answering with automated answers that didn't even took into account what we wrote. (e.g: they keep telling we should be using SNDS/JMRP while my messages starts saying that we use SNDS/JMRP and we get no hints from the 2 tools about the issue).
At the 3rd reply they write "SmartScreen" is the cause and they say SmartScreen is not about IPs (but in fact we see it as an IP issue) and it seems SmartScreen is a blackbox for them (at least for the people answering to their troubleshooting forms). In our case the issue is not with "block lists", but simply different treatment for almost identical IPs, or junking of every email coming from a given IP and sent to a "new address" when SNDS paint it Green with no trap hits and no complaints and JMRP never reported FBL. Our IPs are shared between thousands of customers/users, so if Microsoft doesn't give us any hint about the issue we are not able to work on it. We don't see similar issues to other providers. Stefano PS: for the record my last ticket was SRX1396384464ID (from end of August). It did follow the same path of 3 previous tickets so I gave up trying to understand. Answer is always "The IP is not blocked", it is because of SmartScreen, so it is because of content. But any email from that IP to a new recipient is junked (emails sent to recipients contacted by that IP before the issue appeared are inboxed). -- Stefano Bagnara Apache James/jDKIM/jSPF VOXmail/Mosaico.io/VoidLabs On 18 October 2017 at 09:32, Mathieu Marnat <mmar...@iroquois.fr> wrote: > Hi, > > > I have an issue with Outlook's anti spam rules.
