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.
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 [22.214.171.124] said: 550 5.7.1 Unfortunately, messages from [10.10.01.01] weren’t sent. Please contact your […]
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 […]
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 […]
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. https://sender.office.com Submit your IPs and it will be reviewed. (Apologies for the repeated bad links. I’m […]
One of the new bits of information to come out of the EEC15 deliverability discussions is how Hotmail is looking at engagement differently than other webmail providers. Many webmail providers really do look at overall engagement with a mail when making delivery decisions. And this really impacts new subscribers the most. If there is a mailing […]
Welcome to a whole new year. It seems the changing of the year brings out people predicting what they think will happen in the coming year. It’s something I’ve indulged in a couple times over my years of blogging, but email is a generally stable technology and it’s kind of boring to predict a new […]
Looks like Hotmail / Microsoft is having a rather bad day. Their DNS seems to be intermittent. While they were down a while ago they were returning SERVFAIL for some DNS lookups, including MX lookups. For senders who have the DNS data in their recursive resolvers, this will have no impact. For senders who either […]
ISPs are continually developing tools for their users. Some of the newer tools are automatic filters that help users organize the volumes of mail they’re getting. Gmail released Priority Inbox over a year ago. Hotmail announced new filters as part of Wave 5 back in October. All of these announcements cause much consternation in the […]
Microsoft announced a number of changes to the Hotmail interface today. It doesn’t look like this will affect how mail is received, but will affect how users can interact with it. As always, the best advice I can give you is send mail people want and like.
