I am sure you are guessing right. Do you also check their SPF records? Here in Canada, internet shops are being taken over by Shopify. I am not saying that big service providers like Microsoft, Google, Shopify, etc. are inherently bad. Economies of scale predict that such large outfits can be very competitive. What I am saying is that where network effects are important, or as in the case of internet email, critical, these large outfits have an incentive to use their scale for anti-competitive behavior, such as arbitrarily rejecting mail from competitor's services. Nothing prevents you or me from developing an online retail solution and compete with Shopify. But if we try to operate a mail server and can't deliver emails to a large number of potential recipients, no one will contract our services and we will be prevented from making a run on Gmail/Outlook. I am not saying Microsoft is doing that -- there is ample evidence that its filtering service is going ballistic against mail coming from its own cloud. I am saying that the unintended consequences of Microsoft's filtering are difficult to distinguish from intended anti-competitive behavior. What is more important is that intentional or not, this behavior is detrimental to internet email and has to stop before internet email becomes even more irrelevant.

No. Internet email suffers indeed a governance problem that result in interoperability or deliverability difficulties, but government monopolies are not the solution. Government's role is to set the rules and police them, not to provide the service that can be competitively provided by private enterprise. The corollary you envision is the phone network of the Seventies. Today, in advanced countries, the phone network is a more or less competitive market, that unlike internet email is *regulated* by government and *co-ordinated* at the ITU-T, a UN agency. I am not proposing that exact model (a license is required to operate a telecom and I rather see less red tape than more) but I am proposing that standards be enforced, and extended to include a sufficient level of deliverability. Today, "standards" are imposed by the big players, and they do so very much in the bad Microsoft way of the nineties: Embrace, Extend, and Extinguish. Internet email may not be extinguished any time soon, but it is becoming less and less relevant, replaced by SMS/MMS and other proprietary messaging platforms (iMessage, Whatsapp, Telegram, etc.) that do not suffer the governance problems that come with the cacophonic fragmentation of internet email space where sender identification flaky and filtering is not only not standardized, but also spurious to a point of unreliability. > I do not expect this to garner much support by anyone currently > running any sort of commercial mail service on either end. Of course not. There is more money to be made in a world of deliverability issues and in the long term using deliverability as a way to squeeze out of the market the smaller players and aim for an oligopoly or even a monopoly, resulting in higher prices and less innovation. What volume of maiboxes is handled by the three biggest service providers in your country? Not talking free consumers services. It has been a long time since I have dealt with another business whose mailboxes were not handled by either Microsoft or Google. Choose your poison. Internet email in its pure form was/is a sore pain for profitability: there is an unlimited number of domains available (unlike the limited and controlled range of phone numbers or IP addresses) and barriers to entry were very low.

Your mileage may vary. Around here several clients and vendors moved to Zelle or other electronic payment mechanisms due to persistent problems with snail mailed checks never arriving.

Toward the end of my careen at MS, my analysis of the architecture that the system was evolving toward (on the O365 side) told me that it should be possible for a message to completely disappear without the possibility that any plausible investigation process would reveal why (or even if) a particular message met a particular fate. This architecture has been carried over into the "unified" system, with considerable elaboration. I often use the term "apparently occasionally non-deterministic" for the platform. Having watched the system behaviour from the outside for the past eight years, I have found no reason to alter this impression. I doubt strongly that there is any individual with a full synoptic grasp of the System itself. >With that being said, they try to help senders, much more than a lot of other >mailbox providers. Certainly most of the individuals I worked with had a keen understanding of the issues facing all the parties. The problem is that those who make budget decisions or control the deployment of resources in the Corporation will often have disjoint understandings and a different set of primary objectives. (Then there was our Search for that individual or group who were actually required and empowered to read and answer abuse@ and postmaster@...) >Filters are not static, they are adjusting all the time.

If the problem persists, stop for 24 hours.) has proved to be worthwhile. Fortunately, on the platform my clients are using, implementing that for any recipient system is trivial. >MS users and MS policy makers are about the only folks who are going to be >able to change what MS is doing.

"Microsoft" and "Systems Microsoft is presently running" are distinct entities, often with no discernible connection other than the accidental. When it was possible to do so, I spent a considerable amount of my work day investigating reported false positives, and fixed a lot of unneeded damage. Eventually I was reassigned. In the end, however, "How to prevent CEOs of large client corporations from calling Rajesh Jha in the middle of the night because of massive spam problems" will become "How to prevent Rajesh Jha from calling ME in the middle of the night due to client spam problems", which will then tend to drift to the top of one's priorities. (Rajesh Jha was $BIGNUM pay grades above us all, at the time.) I will point out to the assembled multitude that the world of email experienced by a spam analyst at Microsoft or Y!/AOL or gmail is remarkably different from the world of email experienced by someone trying to operate an ethical and effective email sending operation, or to advise those that do.

I am reasonably familiar with Microsoft’s anti-spam systems and how they work. They do block ranges, and subnets, but anyone claiming that AS(whatever) means that MS is blocking autonomous system number(whatever) is flat out wrong. That is not what that diagnostic code means. > Or silently discarding mail... come on, that's just the worst practice ever. I silently discard mail all the time. No one, absolutely NO ONE, is entitled to my time or attention or mailbox space. That goes double when the mail is actively harmful. If MJW says that shouldn’t be happening in the freemail domains any longer, I believe him. On the O365 side, individual administrators have the ability to discard mail on their own systems for their own domains. Neither you nor I have any right to tell those administrators they cannot do that. Not our systems, not our rules. Look, Microsoft has tons of flaws. They have an aggressive blocking system that upsets a lot of senders. They have stupid rules and implementations that I don’t think do what they think they do or even what they’re intended to do. I think the system has accreted and evolved to a point where not even the folks inside Microsoft can tell you why a mail was delivered where it was. I mean, that’s been true for more than a decade now. It’s not, somehow, that the folks answering sender support mail won’t tell you, it’s that they can’t tell you. I suspect that even the system developers couldn’t tell you exactly why a mail went to bulk or was discarded or was rejected. Machine Learning filters (and it’s all ML filters these days) simply don’t work that way. With that being said, they try to help senders, much more than a lot of other mailbox providers. They were the first company to offer data directly to Senders (SNDS). They were one of the first groups to offer FBLs. They are the ONLY group I am aware of that actually asks their users directly whether or not their spam filters are doing things right in that user’s mailbox. Not some random ‘do you like our filters’ but a specific pop up window that says to a user: "We put this email in your spam folder (or inbox). Did we get this right?" It is phenomenally hard for a new sender to break into the MS inbox. For client reasons I ended up doing a bunch of tests yesterday and the first mail from my IP went to bulk. I hit ’this is not spam’ and the second mail from that same IP and sender combination went to the inbox. The third email from a different sender but the same IP went to spam. That’s basically what I needed to know so I stopped testing at that point. Yeah, Microsoft hates low level senders. Microsoft hates new IPs. Complaining on mailop isn’t actually going to change anything about that. Complaining to the developers over beer in the pub isn’t going to change that. Complaining to the product managers isn’t going to change that. O365 is widely used and we’re stuck with it. The free domains are less widely used than Gmail but they’re still in the top 5 per volume for most mailing lists. A few additional facts: SmartScreen is partially based on the above mentioned ‘did we filter this mail correctly’ questions. It’s also based on user complaints. It’s based on the content of the mail, it is unrelated to IP or even domain reputation. Call it stupid all you want but the reality is: Smart Screen is a measure of how much recipients want a particular email stream. If they’re saying they don’t want it, then Microsoft is going to listen to what their users tell them. Some of the measurements are based on explicit user questions, others are based on user interactions with mail. Filters are not static, they are adjusting all the time. Sometimes ‘just keep trying’ is the right thing to do. Sometimes ‘give it a rest for a week (or 2 or 3) and let your reputation reset’ is the right thing to do. Sometimes it feels like there is nothing the sender can do to change delivery. MS users and MS policy makers are about the only folks who are going to be able to change what MS is doing. It sucks for those of us who are looking at the mail in our outbound queues and going ‘yknow, this person paid for this email and MS isn’t letting me deliver it” or “this person probably really wants their appointment reminder, but MS isn’t letting me deliver it” or “Auntie susie really wants to hear from cousin joan, sucks microsoft doesn’t like this” but complaining on mailop isn’t going to change any of that. If complaining on mailop fixed MS filters, then they would have been fixed a decade ago. We’ve been having this same discussion for that long. laura -- Having an Email Crisis?

Re: [mailop] protection.outlook.com refusing to accept mail with misleading temp error message
Hello, I'm rather new to this list, so I hope it's okay to jump in directly in this discussion and share some thoughts. :-) I just recently faced a very similar problem with one of the new IPs I got assigned. Likely, the IP was in use by someone else previously or there are spammy neighbours (not surprising when it's a big provider with some customer turnaround). I got all deblocking done in the various blocklists, the status was clean everywhere, including SNDS, but still, Microsoft 365 mailboxes (*.protection.outlook.com) blocked it. It seems there are various independent blocklists - one set is covering consumer Outlook/Live/Hotmail, the other set is covering Microsoft 365. SNDS seems to only query the former one, and the Outlook.com web form only unblocks on these domains, so neither of that helps for Microsoft 365 mailboxes. For Microsoft 365, there seem to be various levels of blocking. Sometimes, you can unblock yourself at sender.office.com, but I hit the infamous "Write to delist@" message. I managed to create a ticket there, they asked for some details, but then radio silence, all follow-up mails ignored, for over a month now. Various ways of contacting them went without any outcome, and I sense that on their end there is also some confusion as to the existing blocklists - I got repeatedly told the IP is not listed (which is what sender.office.com told me too), or to use the Outlook.com form, that obviously didn't help for my problem at hand. In the end, via way one of the communication channels I tried, I somehow managed to get a supporter who was really engaged and managed to helped me out, but I must admit that the whole process was not straightforward and took me a month in the end. At least when people provide full contact data/imprint and proof that the IP was freshly assigned, some feedback would be good to not be left in the dark. Problematic is also that there is no actual way to test if your new IP is blocked before using it, apart from sending to an actual e-mail address hosted there.

All what recipients AND mailers want is a reliable email service, like snail mail. I don't like the invoices, solicitations, and other things that land in my snail box, but I do like the fact that if someone puts a letter with my address in a post office box anywhere in the world, it makes its way to my snail box within a reliable service standard. The result of this attitude is that users are pushed to alternatives. iMessages, Telegram, SMS, you name it.

I don't think anyone has said that. Microsoft's mail systems have accreted over the years and are held together with chewing gum and baling wire. On the other hand, if the recipients of the mail don't complain when they don't get it, it's hard for the mail system operator to feel very motivated to do anything about it, whether Microsoft or anyone else.

Re: [mailop] protection.outlook.com refusing to accept mail with misleading temp error message
The issue - at least to me - has always been that Microsoft is viewed as this big, huge company that can do no wrong. When our users have issues sending to Microsoft email servers - it's obviously because *we're* stupid and something is wrong with *our* server. It can't possibly be a Microsoft issue. Microsoft made Windows, what did we make? That's the narrative that needs to change. If end-users would somehow start to realize that Microsoft has a horrible email system, fewer people would be inclined to use Microsoft based email accounts. That's basically what we have done. I'm sure we've probably lost some clients over it. But if you're using a Microsoft based email address for anything mission critical, then I'm sorry, you're probably missing stuff. And not just stuff from us, but from any number of other places. Missing stuff could be because of a no reason block/blacklist or just a silent deletion of the message.

Re: [mailop] protection.outlook.com refusing to accept mail with misleading temp error message
Hi, It's unfortunate to see others experiencing the same issues we've had with Microsoft in general. We're not a massive player in the market and constantly experience these service-disrupting incidents with MS and Office365. (Side note - I am also personally a paying premium customer of outlook, so I expect MS to do a proper job with that platform. It's not a "free, so we don't care" system) A thought - Has anyone approached Microsoft/Hotmail and suggested a working group with them? The working group would be representatives of trusted mail host operators and senior admins in MS, understanding that by creating this group, we're reducing both their workload and increasing their customer satisfaction. The goals would be to find solutions for 1. A way to quickly escalate any blocking issues from our IP ranges 2. Establish valid mail trust with our IP ranges, knowing that we are doing everything in our power to limit spam. 3. Establish that mail from these IPs may vary in volume 4. Have the ability to inform MS of new IP addresses, so they don't block them for sudden rate change 5. Help understand ways we can change our systems to reduce the chances of being blocked/deleted/listed I could approach some contacts at Microsoft and see if they're willing to do such a thing?

We're not talking about bulk mail here. We're talking about messages between individual users, including such things as doctor or vaccination appointments, meeting schedule coordination, etc, which both affected parties consider important. Some occasional small mailing lists for group information exchange, too. No marketing stuff, social media notifications or other noise that people wouldn't miss. I'm pretty strict myself when it comes to blocking spam-emitting sites. And of course, it also happens that we block some IPs or IP ranges due to spamming and some time later it turns out that the same hosts are used by legitimate senders. We have several mechanisms in place to detect and remedy such situations quickly. And when we notice spam floods (such as the current hotmail bot flood) from mail systems we're going out of our way to implement very specific filters that keep out the drek while allowing legitimate mails through.

Why do you always assume that the issue only refers to bulk mail? I ran once, a few years ago, into an issue where my purely personal messages, to someone I know, who had email hosted on O365, have been just silently discarded by MS. Neither me nor the recipient knew about this, until we figured out something is wrong and managed to contact using another means. (A similar situation is with Gmail putting my messages into Spam folder, which happened to me a few times). So using your (and Microsoft's) logic, the recipient "did not want" that mail, and "didn't care" that she didn't get it, because she didn't complain to MS that she didn't get it. Which was obviously not the case. And she couldn't complain because she didn't know in the first place that I send her that email. It was good that I had a different way of contacting that person. But what if the only contact was email? Let's assume for example that the recipient is you. You are quite a famous person ;), among others because of a few books you wrote. Some of those books contain your e-mail address, so it's quite normal that you can expect e-mails from your readers. Assume I'm a reader who wants to contact you - for example to ask about something I read in your book or just to express my opinion. But my email gets discarded or rejected. You don't know that I wanted to write to you, so you can't even tell whether my e-mail was wanted or not (according to my criteria, an author can never call messages from his readers "unwanted", even if they just hate him). But according to your logic, since you never worried that you didn't get my email (which you didn't know about at all), you didn't want that email. See the absurdity? -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." ___ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop

The capitalistic answer is to make the provider responsible / liable for the damages caused by its non-reacheability.
