Microsoft deprecating SmartScreen filters

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 […]


Hotmail having a bad day

Hotmail seems to be having a bad day, responding to a lot of delivery attempts with “554 Transaction failed” responses. It’s not you, it’s them. They’re aware of the issue.

Ask Laura: Is the SmartScreen Filter Really Smart?

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 […]

Getting unblocked at

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 […]

Thoughts on Hotmail filtering

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 […]


Mythbusting deliverability and engagement

Yesterday I published an article talking about an engagement webinar hosted by the EEC and DMA. I made a couple predictions about what would be said. ISPs do monitor engagement, even if they do it differently than senders thought. Engagement is important for inbox delivery at some ISPs. Different ISPs have different ways of making […]


Email predictions for 2015

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 […]

ISPs speak at M3AAWG

Last week at M3AAWG representatives from AOL, Yahoo, Gmail and Outlook spoke about their anti-spam technologies and what the organizations were looking for in email. This session was question and answers, with the moderator asking the majority of the questions. These answers are paraphrased from my notes or the MAAWG twitter stream from the session. […]


Hotmail having a bad day

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 […]

  • Vague reports of Yahoo problems

    A number of people, on different forums, have been asking if anyone is seeing a higher bounce rate than usual with Yahoo. Not sure exactly what's going on here. As I understand it, folks are talking with Yahoo about it. If I hear anything more, I'll share. For now, though, if you're seeing a small increase in Yahoo bounces (or other weirdnesses) others are seeing something odd, too.No Comments

  • Brief blogging break

    Sorry about the unexpected hiatus. I picked up a cold that really made me feel fuzzy and writing was an exercise in futility. I'll be back Monday. Meanwhile, Oracle bought another ESP (Bronto) when they bought NetSuite.  No Comments
