Happy March! Here’s a look back at our last month of email adventures. It was a busy few weeks for us with the M3AAWG meeting in San Francisco. We saw lots of old friends and met many new people — all in all, a success, despite the M3AAWG plague we both contracted. Hot topics at the conference included DMARC, of course, and I took the opportunity to write up a guide to help you determine if...
I’ve been hearing a lot lately about DMARC. Being at M3AAWG has increased that. Last night we were at dinner and heard from the next table “And they’re not even publishing DMARC!!!!” I know DMARC is the future. I know folks are going to have to start publishing DMARC records. I also know that the protocol is the future. I am also not sure that most companies are ready for...
Dear Laura, I have a client moving from an external ESP to an internal system. They send approximately eight million messages per year, and these are primarily survey emails on behalf of their clients. We’ve had some conversations about authentication, and I’m trying to help them figure out if they just need DMARC or if they also need DKIM and SPF. It seems some ISPs prefer different methods, and...

I don’t always do predictions posts, even though they’re popular. Most years I skip them because I don’t see major changes in the email space. And, I’m not the type to just write a prediction post just to post a prediction. This year, though, I do see changes for everyone in the email space. Most of them center on finally having to deal with the technical debt that’s been accumulating over the...
Happy 2016! We enjoyed a bit of a break over the holidays and hope you did too. Here’s our December wrap up – look for a year-end post later this week, as well as our predictions for the year ahead. I got a bit of a head start on those predictions in my post at the beginning of December on email security and other important issues that I think will dominate the email landscape in 2016...
The next step in email authentication is DMARC. I wrote a Brief DMARC primer a few years ago to help clear up some of the questions about DMARC and alignment. But I didn’t talk much about where DMARC was going. Part of the reason was I didn’t know where things were going and too much was unclear to even speculate. We’re almost 2 years down the line from the security issues that...
When the Domain Name System was designed thirty years ago the concept behind it was pretty simple. It’s mostly just a distributed database that lets you map hostname / query-type pairs to values. If you want to know the IP address of cnn.com, you look up {cnn.com, A} and get back a couple of IP addresses. If you want to know where to send mail for aol.com users, you look up {aol.com, MX}...
Looking at the headers within the mail received with my Office365 domain I see dmarc=bestguesspass. BestGuessPass? That’s a new. A few days after seeing dmarc=bestguesspass, Terry Zink at Microsoft posted an explanation. Exchange Online Protection, the filtering system for Office365, is analyzing the authentication of incoming emails and if the domain is not publishing a DMARC record, EOP...
