A c/p from an email I sent to a mailing list. I think we’re seeing a new normal, or are still on the pathway to a new normal. Here’s my theory. 1) Hotmail made a lot of underlying code changes, learning from 2 decades of spam filtering. They had a chance to write a new codebase and they took it. 2) The changes had some interesting effects that they couldn’t test for and didn’t expect. They spent...
People throughout the industry are reporting phishing notices in a lot of mail going through Microsoft properties this morning. I even got one in an email from one of my clients earlier today Multiple people have talked to employees inside Microsoft, and I suspect their customers have been blowing up support about this. I know they’re aware, I suspect they’re frantically working on a...
This is the time of year when everyone starts posting their predictions for the coming year. Despite over a decade of blogging and close to 2500 blog posts, I have’t consistently written prediction articles here. Many years I don’t see big changes on the horizon, so there’s not a lot to comment on. Incremental changes are status quo, nothing earth shattering there. But...
Today on MailOp it was announced that the migration of Microsoft freemail domains to the office 365 backend. Over the next week the mx*.hotmail.com mail servers will stop working. Check your settings, folks, and make sure you’re correctly querying DNS before sending.
October was a busy month. In addition to on boarding multiple new clients, we got new desks, I went to Toronto to see M3AAWG colleagues for a few days, and had oral surgery. Happily, we’re finally getting closer to having the full office setup. What is an office without a Grover Cat? (he was so pleased he figured out how to get onto it at standing height). All of this means that blogging...
Microsoft is still in the process of rolling out new mail servers. One thing that is new about these is some new codes on their error messages. This has led to questions and speculations as to what is going on. host outlook-com.olc.protection.outlook.com [104.47.9.33] said: 550 5.7.1 Unfortunately, messages from [10.10.01.01] weren’t sent. Please contact your Internet service provider since...
There’s been quite a bit of breakage and delivery failure to various Microsoft domains this month. It started with them changing the MX for hotmail.co.uk, then the MX for hotmail.fr… and both these things seem to have broken mail. I also saw a report this morning that some of the new MXs have TLS certificates that don’t match the hostnames. What’s going on? Historically...
At the beginning of the month Microsoft announced that they were deprecating the SmartScreen filters used by the desktop Microsoft mail clients. These are the filters used in Exchange and various version of Outlook mail. This is yet further consolidation of spam filtering between the Microsoft free webmail domains, Office365 hosted domains and self hosted Exchange servers. The online services...
Dear Laura, Can you help me understand the Microsoft SmartScreen filter? I’m working on a new project and we’re not able to get to the inbox at Microsoft. Our SNDS/JMRP health is great, not a problem that we can see, but when we contact the support team we’re told we’re being flagged by SmartScreen. It seems impossible to try and find any information or ways to rectify this issue...
It’s been a crazy week here at M3AAWG. I have a lot of stuff to blog about, but I think one of the really important things to get out is the new unblock request page at Outlook / Hotmail. Submit your IPs and it will be reviewed. (Apologies for the repeated bad links. I’m blaming con crud, lack of sleep and MSN/Hotmail/Office/Outlook for having so many domains I can’t keep them...
