The email solicitation that made me vow to never work with this company again. When sending unsolicited email, you never know how the recipient is going to respond. Writing a public blog post calling you out can happen.

5 CAN SPAM myths. Send Grid’s General Counsel speaks about CAN SPAM myths. Personally, asking for an email to unsubscribe is annoying. I never know if the unsubscribe request worked or not. Give me a link any day.
The most misunderstood statistic in email marketing. A good discussion of why raw complaint rates isn’t the metric the ISPs use, and how it can mislead folks about their email program.
Office 365 is expanding it’s DKIM signing. Terry Zink discusses the upcoming changes to how Office365 handles DKIM signatures. This is exactly the kind of changes I was talking about in my 2016 predictions post – background changes that are going to affect how we authenticate email. He even specifically calls out whether or not a particular signature is DMARC aligned or not.

Monetizing the complaint stream

What if ESPs (and ISPs, for that matter) started charging users for every complaint generated? Think of it like peak pricing for electricity. In California, businesses can opt for discounted power, with the agreement that they are the first companies shut off if electrical demand exceeds supply. What if ESPs and ISPs offered discounted hosting rates to bulk senders who agreed to pay per complaint?
I see pricing scheme something like this.

Spam, Phish or Malware?

Some mornings I check mail from my phone. This showed up this morning.
PizzaHutMail
My first thought was “oh, no, Pizza Hut is spamming, wonder who sold them my address.”
Then I remembered that iOS is horrible and won’t show you anything other than the Friendly From and maybe it was some weird phishing scheme.
When I got to my real mail client I checked headers, and sure enough, it wasn’t really from Pizza Hut. I’m guessing actually malware, but I don’t have a forensics machine to click the link and I’m not doing it on anything I can’t wipe (and have isolated from the rest of my network).
The frustrating thing for me is that this is an authenticated email. It not from Pizza Hut, the address belongs to some company in France. Apparently, that company has had their systems cracked and malware sent through them. Fully authenticated malware, pretending to be Pizza Hut, and passing authentication on various devices.
Pizza Hut isn’t currently publishing a DMARC record, but in this case, a DMARC record for Pizza Hut wouldn’t matter. None of the email addresses in the headers point to Pizza Hut.
I spent last week listening to a lot of people discussing DMARC and authentication and protecting people from scams and headers. But those all the protocols in the world won’t protect against this kind of thing. Phishing and malware can’t be fixed by technology alone. Even if every domain on the planet published a p=reject policy, mail like this would still get through.

A brief history of TXT Records

txt
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} and you get a set of four hostname / preference pairs back. If you want to know the hostname for the IP address 206.190.36.45 you look up {45.36.190.206.in-addr.arpa, PTR} and get a hostname back.
There’s a well-defined meaning to each of those query types  – A is for IP addresses, MX is for mailservers, PTR is for hostnames – and that was always the intent for how DNS should work.
When DNS was first standardized, though, there was one query type that didn’t really have any semantic meaning:
