> In early 2024, Google and Yahoo began requiring
Here's a big part of the problem right there. Google requires something, it becomes a requirement. In fact, Google's hold on email is a problem in itself. Among other things we need variety. Without it, "Google begins requiring" will be a recurring theme. It's happening again now with mobile phone apps! "Google begins requiring" that you register with them so that the apps you write can be installed on Android phones.
> This shifted authentication from something senders could deprioritize to a basic prerequisite for reaching inboxes.
And later, Google and a few other large players could just prevent individuals and smaller email service providers from being able to send email, at all.
> so the filtering systems can tell where bad content is coming from and avoid hurting the reputation of the wrong parties.
Be ready for people who don't register with the big corporations to be marked as having "bad reputation" and being simply blocked. There might be some technical excuse.
> The inbox of the future will be faster, smarter, and more capable than what most of us use today.
That sounds like the inbox of the future might be controlled by somebody else. I don't like that at all.
Disclaimer: I do some work for one of Gmail's competitors.
Of all the stuff Gmail imposes on the rest of the world, requiring proper sender authentication was a good thing and we've helped thousands of senders set up proper authentication because of it.
Forcing the issue finally got rid of the ridiculous practice of ignoring SPF/DKIM failures and just setting the DMARC record to p=none.
None of this changes the fact that Gmail is a problem for so many other reasons, but this specific imposed change was a net benefit for the entire email ecosystem.
Honestly requiring DMARC was overall a good thing.
I was an email admin for a university. In the past - each college ran their own email. Before DKIM, before SPF, you'd just have basically random servers on the internet sending email as (school).edu. Tons of random subdomains too. math.(school).edu and so on.
Email was eventually centralized but you'd have parts of the university still running their own things. Insisting they're special and can't be brought into the fold.
So, we had a lot of stuff out there just not passing authentication. A lot of spammers could just impersonate our domain.
We'd go to leadership and say "hey we should really get our act together" - but everything was working. Our emails were still getting out. Hard to justify spending the time, getting various higher-ups within departments to give up their things, and so on.
Unless you can get like, the president to back your initiative- universities are very decentralized and it becomes an issue of "do we have the political capital to spend here." The overall relationship between central IT and the various college-based IT departments was terrible, often bordering on combative.
Google and Yahoo made it so we could go to leadership and say "people will not get our emails if we don't get this straightened out" and it became a priority. When I left our DMARC reports were showing something like a 99% pass rate when it was previously like, 50.
So, I'm glad Google and Yahoo made that call, it gave us the kick in the pants we needed to get our own shit together. I am 100% certain we were not the only org like this.
Plus for a small host - where you're just running a single mail server or something - you just need a few things to pass DMARC.
A DMARC record, and an SPF record, and for your emails to pass SPF. You technically don't need to do DKIM signing (though I'd still recommend it because that survives automated forwarding).
