   For one thing, you can configure a DMARC policy without a reporting address. For another thing, you can use third-party services, such as https://dmarc.postmarkapp.com/ , to aggregate DMARC reports for you (if you're fi

   I chose the name of the blog to mean analytic, reductionist reasoning (in contrast to associative, vague reasoning). In the meantime, I also like the following framing, which I wanted to add to the front page of the blog for some time: htt

   This is a valid question. I'm the author of the blog and I've asked this myself in the past. The main reasons why I haven't done this so far are - artistic freedom (regarding the form/structure, the style/tone, the

   Hi layer8, thanks for the feedback! I must say that your standards for thoroughness are pretty high. Since I claimed at the very top that my article covers all aspects of modern email, I don't mind your criticism at all. I haven'

   For me, "from first principles" is not the same as "elementary". It's just about "reductionism" and answering all (or at least most) "why" questions. Let me know if you find any gaps in the expla

    As the title before this very sentence says, this is the outline of the whole article/"book". Since it is a web page, I link to the corresponding chapter instead of mentioning the page number. The very first chapter starts wi

    Hi, I'm the author of the article/"book" being discussed here. :-) I'm fully aware that the article isn't for everyone, but I can't see what's wrong with outlining the structure of a book in its intro

    Thank you for your feedback. I see how this can be confusing. The first chapter is explicitly about user-facing concepts, though. I explain message envelopes here: https://explained-from-first-principles.com/email/#mess

    Yeah, I'm sorry about this. I realized this only once the post was live. I will see that I can fix this. Did you access the page with Firefox? And don't worry, it's nothing malicious. It's just the ESMTP tool, which has

    Just to be precise: It's a single From field with several addresses, not multiple From fields (see https://tools.ietf.org/html/rfc5322#page-21 ). RFC 6854 updated the From field to allow an empty group construct (s
