Let’s Talk: FBLs

let’s-talk:-fbls

Next Delivery Discussion Wednesday, May 20. We’ll be talking FBLs. I’ve been reviewing the recording of last week’s call. A few folks have reached out and asked that their comments not be shared, so I am working out next steps. The good news is that the recording worked well and I’m learning new skills. Please RSVP to laura-ddiscuss at the obvious domain. Invite will go…

Spamtraps resources

spamtraps-resources

We had a well attended call yesterday, almost 40 people showed up. I did get a recording but need to work out some editing before sharing it. What did you do during the pandemic? I learned lots of new things and spent way to much time relearning all the virology and immunology I forgot after leaving the lab… I do have the google doc of…

Deliverability is nuanced

Still doing invites manually, so drop me an email at laura-ddiscuss@ the obvious domain. A few weeks ago, the discussion entered around machine learning in general. As a follow on I’d planned…

Machine learning resources

machine-learning-resources

Thanks to everyone who joined the deliverability discussion on Friday. I realised after I scheduled that it was Good Friday and that may have limited some folks’ ability to join. This call we talked about Machine Learning and how it is applied to spam filters. Before the call I put together some resources in a Google Doc and some participants added links and more information…

Spamhaus DBL errors

spamhaus-dbl-errors

Sometime in the last few days, Spamhaus seems to have started issuing a block message if someone queries the DBL with an IP address. folks started seeing an uptick in error messages that mention Spamhaus saying: 554 5.7.1 Service unavailable; Client host [x.x.x.x] blocked using dbl.spamhaus.org; No IP queries, see https://www.spamhaus.org/faq/section/Spamhaus%20DBL#279 (in reply to RCPT TO command)) Crowdsourcing information from the emailgeeks slack channel makes…

Whose side are you on?

whose-side-are-you-on?

A few weeks ago I was on an industry call. We were discussing some changes coming down the pike at the ISPs and filter providers. These changes are going to cause some headache at ESPs and other places that do email but don’t provide mailboxes. During the call I ended up explaining why what the ISPs were doing made sense and how it fit in…

Misinformation on filters

misinformation-on-filters

I’ve seen reports that someone is asserting that utm=COVID19 in URLs results in all mail going to bulk at multiple ISPs. This is the type of thing that someone says is true and dozens of folks believe it and thus a “deliverability phact” is born. For a plethora of reasons, this doesn’t pass the sniff test. Don’t believe everything you read on the internet. It’s…

Discussion Session

discussion-session

More than 30 people joined our delivery discussion from last Wednesday evening (Irish time). Thanks to all who joined and participated. I had a number of different topic suggestions, but the thing on everyone’s mind was the current pandemic and how much email many of our customers, clients, and companies are sending. We had what I think was a productive discussion sharing information and experiences.…

Deliverability discussion

deliverability-discussion

Lots of folks are socialising distantly these days, so I thought I’d try a scheduled deliverability discussion over video. Given the time difference, I’ll log on in the evening Irish time which makes this daytime for most of the US folks. The first call will be Wednesday, March 25, 2020 at 5pm Ireland time. That’s 1pm Eastern and 10am Pacific. If you’re interested in joining,…

Happy St. Patrick’s Day

happy-st.-patrick’s-day

It’s a near silent St. Paddy’s day here in Ireland. We took a walk along the canal and took in the silence. On the way back, our neighbour’s kids had decorated their front window and I had to take a picture. Things are weird. Be kind to yourself and to others. Wash your hands. Don’t touch your face. Don’t send that email to your entire…

Authentication at Office365

authentication-at-office365

This is a followup from a post a few weeks ago about authentication changes at Office365. We have some more clarity on what is going on there. This is all best information we have right now. Microsoft is now requiring authentication to match the visible from address in order to reach the inbox at Office365. That means, either the SPF domain or the DKIM domain…

Back at it

back-at-it

Back at the office after traveling to visit a bunch of our US friends recently. A lot of news, both in and out of the email space, happened while we were gone. The biggest stories are outside the email space and I will admit to following the coronavirus news probably closer than I should. (My graduate work was done across the hall from one of…

Address verification doesn’t fix any real problem

Would you trust an address verification company that used twitter spam to advertise their product? Would you trust an address verification company that sent email spam to advertise their product? Would you trust an address verification company that sent email advertising their product to made up addresses? Would you trust an address verification company that sent email advertising their product to spamtraps? Would you trust…

The OSI Seven Layer Model

the-osi-seven-layer-model

In the 1970s, while the early drafts of the Internet were being developed, a competing model for networking was being put together by the ISO (International Organization for Standardization). The OSI (Open Systems Interconnection) Model broke the work needed to implement a distributed network service into seven separate layers of abstraction, from the physical infrastructure at layer one all the way up to the application…

Some Microsoft thoughts

some-microsoft-thoughts

Right at the end of January, Microsoft appears to have made couple of changes to how they’re handling authentication. The interesting piece of this is that, in both cases, Microsoft is taking authentication protocols and using them in ways that are slightly outside the spec, but are logical extensions of the spec. The first is an extension of DMARC. They’re rolling out inbox flags for…

Your first M3AAWG meeting

your-first-m3aawg-meeting

It’s that time of year again where nearly all my client calls involve the question, “are you going to be at M3AAWG SF?” Up until last year, the answer was always yes. But now it’s not a brief drive up the peninsula and a BART ride into the city, it’s a transatlantic plane flight. The clients I was talking with today said this was their…

Troubleshooting: part 3

troubleshooting:-part-3

As I continue to think about how people troubleshoot email delivery I keep finding other things to talk about. Today we’re going to talk about the question most folks start with when troubleshooting delivery. “Did ISP change something?” At least once a week I check some delivery or email fora and some form of the question is sitting there. “Did X change something? We haven’t…
