Interesting history and analysis of SMTP’s history. How can we prevent fedi and other open protocols from suffering the same fates?

You can’t successfully use a home email server.

Mostly true (server can be home but using the ISP network directly probably won’t work)

You can’t successfully use an email server on a (cloud) VPS.

Bullshit

You can’t successfully use an email server on a bare metal machine in your own datacenter.

Bullshit

As such, it is my distinct displeasure to declare the death of SMTP. The protocol is no longer usable. And as we can see, this devolution occurred organically.

Calling complete BS on that. I work in a medium size company and we do just that. Don’t know what he’s thinking.

Can, yes.

Should, maybe.

Enjoy doing, unlikely.

And for sure your home isp has all the email ports blocked upstream.

With all that being said, to call SMTP dead is wildly insane. I do figure it will die someday though. Probably around the same time of universal IPV6 adoption during the year of the linux desktop.

My ISP doesn’t. It an electric company that offers fiber, so not your typical telecommunications company. Still though, not a single blocked port.

On topic, I tried an email server and it is too much of a pain in the ass IMHO, without the requisite training and experience, but certainly not impossible.

My most recent ISP does CGNAT. They don’t hide it, it’s mentioned in their support pages. A quick email is all it takes to switch you over to an open address though.

Anyway I’ve got a $5/mo server with akami that looks after my email and it’s associated domain.

It took about three hours of following a guide to set up DMARC and etc etc and it works unobtrusively, and is about ten times faster than my old ISP IMAP account that I had for about twenty years.

Same here. Static IP though. I did set up another experiment with a haproxy vps just to see if I could do it if I lost my static IP, worked perfectly done that way too.

Fail2ban, pfblocker, and soamassassin work great.

Yeah. I’ve had zero problems hosting my mail on a bare metalachine in a datacenter. They arrive just like they should, plus it’s just so freeing to host it yourself.

Sure, you can run one, good luck getting even a halfway decent delivery rate to mailboxes at any major mail provider. Even if they never receive a spam message from your server, your server is an “unknown” which counts against you. And if one person in your small company of 10 or 100 or even 1000 people gets their e-mail hacked and sends spam? Prepare for the rest of them to get punished for it. Running an SMTP server is a nightmare which is why, over time, more and more of the economy has just shifted their SMTP servers to organizations who professionally run SMTP servers instead of having their own.

Set up dkim/SPF properly, make sure the ip you plan to use is clean before you start, sign up for MXtoolbox blacklist alerts and if you get on a blacklist (doesn’t happen often if you do a bare minimum of proactive security), you request removal. It’s really not hard.

Right, but try doing that with a 10 day old server created in 2024. That’s the hurdle people are referring to.

I work as a Sysadmin for a web host who sells VPS’s. I’ve helped many people setup domains on their server to cover SPF, DKIM and DMARC passes on a daily basis. Most use these for personal or business level mail delivery without issue.

Are there hurdles to overcome? Sure. But it’s not exactly hard as long as you have a IP that’s isnt a poor reputation (which as an ISP we help delist and improve). But it’s not impossible.

Its more “convenient” to use a third party mail provider just as Office365 since you pass on all that setup and responsibility onto their framework, but it’s not hard to setup a decent level of mail service yourself.

That’s not why people move to big hosters.

They move because you don’t need to waste money managing them, and they have reliable backup

We used to host our own, but big providers are so cheap and have such a good interface that it doesn’t make sense to host our own.

It’s the same reason why most companies don’t host their own web servers.

Even large corporations use AWS or similar.

You’re spot on, and even smaller ISPs routinely get blocked by larger hosters (anyone who doubts this, please look around for the many stories along the lines of “gmail silently drops my email”)

Residential IP blocks are scored much higher and given a negative trust from the start - not surprising since that’s where much of the world’s spam comes from through compromised computers, routers etc.

I know there are problems with big email providers subverting decentralisation to benefit their business models, and throttling mail from independent or self-hosted domains. But I couldn’t take the analysis seriously past this statement:

This guy is a protocol engineer, talking about protocols. You may not like like Bitcoin, but it’s pretty hard to argue it’s not one of the most successful, widely-used, and forked open source protocols developed in the last several decades. Bitcoin core is in the top 100 starred repos on Github. It has a unicode character.

Bitcoin’s market cap (> 1 trillion USD) is bigger than Sweden’s GDP and it moves billions of dollars around the world every year. You can use it to send money to anybody with a phone and a halfway reliable internet connection in under a second for pennies in fees, and it settles instantly. And it’s been working for 15 years without a single hour of downtime, bank holiday, or hack despite pandemics, wars, financial crises, and attempted bans by global powers.

Like, be mad if you want, but it’s a pretty successful and robust protocol. And if you don’t like it, you can fork it and change it, because it’s open source.

http, https, ssh, ntp, ftp. These are all algorithms some of us use every day. Bitcoin is a protocol, true, but it’s not a good one. And it’s one that most people have not used, and don’t intend to

It has a lot of forks? that is neither here nor there. it’s a tech buzzword. of course there are going to be a lot of forks. Do any of them actually go anywhere though? not really

No, see — if I dont like it I don’t need to fork it. I can just leave it and all its forks the hell alone. I’d do the same for national currencies if I could, cryptocurrencies are just the same bullshit without the regulatory checks and balances.

TL;DR — I see what you’re selling and I’m not buying it.

I mean, it’s been shown that it’s relatively easy for a big company to control the price of Bitcoin, and there’s nothing more capitalist than wanting to get away from the control of countries and states that might get in the way of making as much profit as possible so, yeah no I’d say hypercapitalist is a valid accusation. Bitcoin was designed to beat the big banks and capitalist status-quo, but I don’t think that we can pretend it succeeded anymore.

No tech is perfect. And the current bitcoin is not the same as the original client. It has been modified to allow for abuse and control. The fact that we allow this to take place is more a reflection of our governments aiming to control it than any inherent property of the currency.

Big banks would have far less control if you couldn’t print sanctioned currency to buy as much bitcoin as they want to play with the value set by sanctioned exchanges.

I agree that bitcoin is capitalist like most monetary bills in a free market. I disagree it’s more capitalist than what we have now. It’s just being propagandized and veiled from the underlying technology to make it seem so.

Capitalists will even sell you communism if it makes them a dime, end result is cryptocurrency is half assed solving a problem that doesn’t really exist.

Like inflation is a great example, you shouldnt have to add modifiers onto its definition, inflation is inflation - bitcoin by design must inflate

By design, it will slowly stop inflating at the snails pace it does vs unpegged paper currency.

A central bank regulating where money is printed and to whom it’s distributed at what contrived rates is horrifying. It’s also the default in most of the world.

You can trade bitcoin and use it as a currency in a non-capitalist market. The fact that it has been abused and traded into stratospheric value is a result of manipulation, sanctioned exchanges, and propaganda.

Bitcoin just allows you to write debits and credits on a distributed, verified, ledger. That’s it really. How the market is regulated is on the people, not the technology. There is nothing inherently capitalist about the technology other than allowing any individual to trade value with another in a free market manner. You would be trying to escape supply and demand dynamics to remove that “capitalist” aspect of it.

The power draw on the other hand… the first imagining of a digital decentralized and distributed currency was bound to have some problems.

I don’t buy this. I’m still using SMTP on my own domain and it’s working fine, a bit of spam but not unmanageable, real messages get read. Main challenge is digesting so many potentially-interesting list messages, indicating email’s continued dominance for professional topics. Seems this author has another agenda.
Having said that, it’s a pity the world never agreed a protocol for micro-payment for emails (and for many other services), which would resolve the spam problem, and not be a burden for honest users.

I also host my own mailserver and I agree that it mostly works fine. However, there are some email providers that cause trouble:

Google seems to randomly sort some of my mails into the recipients spam folder, while others are delivered fine to the respective inbox. It kinda sucks that you can never be sure whether the recipient actually received your mail or whether they just don’t reply. My IP and domain are not blacklisted on any spam list; SPF, DKIM and DMARC are set up correctly as well.

Even worse is the Telekom (German ISP), who use an explicit whitelist of IP addresses (only IPv4 of course) and require you to display your contact information publicly on a website reachable via the same domain your mailserver uses. Once you’ve set this up you need to message them to be put on their whitelist. If you’re not on their whitelist, they simply reject your mails, they are not even delivered to the spam folder (maybe it’s not worse than Google, because you at least get a notice from your mailserver that your mail couldn’t be delivered). In the end I decided that I don’t care enough to comply with their regulations and just don’t send any mails to Telekom customers.

Aside Google and Telekom, I’ve really never had any issues though.
