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 […]

Once again, we reviewed some of the ways brands are trying (or might try) to improve engagement with customers. LinkedIn, who frequently top lists of unwanted-but-legitimate email, announced that they’ll be sending less mail. Josh wrote about giving subscribers options for both the type and frequency of messages, and about setting expectations for new subscribers. […]

Instead of building a chat application build on a proprietary protocol, Send sends and receives its messages over email and uses your existing mailbox to handle the […]

Office365 checking DMARC on the inbound

According to a recent blog post, Office365 is starting to evaluate incoming messages for DMARC. I talked a little bit about DMARC in April when Yahoo started publishing a p=reject message. DMARC stands for Domain-based Message Authentication, Reporting and Conformance. What DMARC does is allow domain owners to publish policy statements in DNS telling receiver domains […]

Outlook 365 having a bad day

I’ve seen scattered reports today that some mail to the Outlook 365 servers is failing. This has been confirmed by ZDNet. Only folks with a Office 365 account can log in and see the status messages, but there are some folks on the mailop list posting updates from the website. Attempts to mail to affected […]

Ignoring opt-outs

One of the marketing solutions to the spam problem is just to have recipients opt out. We think that commercial e-mail should always — and I emphasize always — provide for a way for the consumer to say: “I don’t want to hear from you again. One bite of the apple is enough. Having heard […]

SNDS News

A number of people have mentioned over the last week or so that they’re seeing a lot of outages, failures and general ickiness with SNDS. I contacted Microsoft and asked about it. SNDS has been undergoing some upgrades and improvements and the outages were not intended to be end user visible. They’re going to keep […]

4 things the new outlook ads tell us about email

Microsoft has a new TV ad showing how trivial it is to remove unwanted email from the inbox. Various busy people use the “sweep” and “delete” functions to clean up mail. The commercial even have a segment counting up the hundreds of emails deleted. This tells me a few things. Email isn’t dead. Major companies […]

DNS, SERVFAIL, firewalls and Microsoft

When you look up a host name, a mailserver or anything else there are three types of reply you can get. The way they’re described varies from tool to tool, but they’re most commonly referred to using the messages dig returns – NXDOMAIN, NOERROR and SERVFAIL. NXDOMAIN is the simplest – it means that there’s no […]

Outlook.com

The big news in email today is Microsoft’s announcement of the next version of Hotmail: Outlook.com. This does appear to be an attempt to compete with a host of Google’s offerings. Not only does Outlook.com include Skype and access to social media accounts, but it also includes web app versions of Word, Excel and Powerpoint […]

  • HE.net DNS problems

    Hurricane Electric had a significant outage of their authoritative DNS servers this morning, causing them to return valid responses with no results for all(?) queries. This will have caused delivery problems for any mail going to domains using HE.net DNS - which will include some of their colocation customers, as well as users of their free services - but also will have caused reverse DNS to fail for most servers hosted by Hurricane Electric worldwide, so if any of your mail is being sent from HE hosted machines you may have seen problems. (We're HE customers so we noticed. Still happy with them as a vendor.)No Comments


  • 65.0.0.0/8 DNS issues

    If you're sending email from any address beginning with a 65 - in 65.0.0.0/8 - it's possible you'll see some delivery problems. Something appears to be broken with dnssec signatures for the reverse DNS zone, leading queries for reverse DNS to fail for anyone using a dnssec aware DNS resolver (which is almost everyone).1 Comment


  • Our green bar certificate is going away

    Later today we'll be switching from an Extended Validation ("green bar") SSL certificate to a Domain Validation certificate. This isn't exactly a planned change but I'm waiting for responses from Comodo before I go into it too much. I'll share some more details next week.3 Comments
