> I'm getting ~10 messages per hour from the same sender and they all get through. I have dragged >100 of these to the junk folder, used some incredibly obscure command on the box (from a 4y old github issue) to see if it's actually being "counted" as spam at all: it is. Now what? Clearly something is wrong; either this filter is as dumb as a bag of nails or it's not working correctly. Good luck figuring it out. I have no idea where to start debugging. Well, if it's of any consolation, I have Outlook365 from work (of course, it's paid), and I have a similar problem where the same sender has been sending spam for several months and I have marked it as Junk (as well as sent a copy to Microsoft for further use) all this while. It still gets through after all these months. I have no idea what the Microsoft email team is working on and how this is even a service for sale to enterprise customers!
