Obligatory PSA: ProtonMail isn't any more secure than Gmail and is likely a honeypot scheme crafted by government agencies: https://encryp.ch/blog/disturbing-facts-about-protonmail/
I know the title of that sounds clickbaity, but they cite their sources. It's worth the read for those curious about ProtonMail's history and their CEOs.
Tbh, that document reads like a discovery channel 2am aliens documentary, but it's not completely without merit.
There are a couple line items about software services they're using that are shitty that sound pretty legit. The fact that they're operating in locations where they might have to hand over data sounds pretty legit. Their warrant compliance and logging/handing over a person's IP address is legit.
The CIA honeypot stuff is all really circumstantial. If the CIA was in as deep as is claimed, a lot of the real evidence people are turning up that they're not a secure as they could be would be unnecessary.
My best guess is they decided to make an email company based in Switzerland with the schtick that they're secure (banks amirite?) They're doing what they can to appear secure without spending too much money. They're not going to have legal battles to keep your data private, and they are going to comply with agencies request for data. Even if they support end-to-end encryption if they are required by an agency to turn that encryption off for you, they're going to do it.
They're probably less likely than Google or Microsoft to sell all of your data to the highest bidder, but realistically there's no such thing as secure email.
The basic assumption every privacy-concerned person should have about email is that it's never secure. Unless you use an offline cryptography program to encrypt your email text and then paste it into the email body before you send it, your emails are insecure.
Email was never designed with that in mind. If you want to communicate securely with somebody, use a medium/method that has been designed from the start for that purpose.
I use ProtonMail because it's not a massive corpo and it's open source, but I don't believe that my emails are significantly more secure than on a service like Exchange or Gmail.
This has been my thinking about ProtonMail, even after reading the article on here, and even after reading https://digdeeper.club/articles/email.xhtml (which I have to reread because it keeps getting bigger).
There is no perfect solution, just different levels of trust. That is right, if I want to be "secure" I got to act like a journalist and use a temporary solution or something that has end-to-end encryption.
Besides, email is meant for public communication. No reason to elevate it into some something it will never be.
Yeah. In my experience, you have to be careful in the world of tech privacy/FOSS to not fall off a cliff to the extremes.
You can always find reasons to not trust some piece of tech hardware or software. It's all too complex and multifaceted to fully vett, and even when you can do that, there isn't anything that isn't touched in some way by mega-corps or glowie agencies.
Tor was developed by the US gov, same with the ancestor of the internet. Your network traffic runs on mega-corp wires, through mega-corp servers. Your hardware is developed, built, and distributed by mega-corps, as is most the firmware and microcode in them.
Even Richard Stallman, one of the most hardcore Free Software advocates has concessions he makes for firmware, microcode, and so forth.
The only way to be truly and completely secure tech-wise is to pull a Ted K. And go run into the woods and live in a little cabin, disown any tech built after the turn of the century lol.
It's "all or something" not, "all or nothing." Determine your threat model, your ethical bounds, and let those principles guide you. I think fundamentally what all FOSS folks have in common is the idea that the tech you use should serve your needs and desires, not the needs/desires of billion dollar mega-corps farming you as a product.
This is the most sane perspective I have read. For sure it is important to have solid principles and do the right things whenever possible, but no one gets to demand changes for something they never contributed to, especially not those things that took a massive amount of money and human power to build. We are all standing on the soldiers of giants, and it is insane to think we can be Ratatouille, controlling them for out benefit.
The only way to change governments and mega-corps is to make it unprofitable when they do the things we don't like, or make it so doing the right thing makes them lots of money.
Thanks for this, it is the reality check I need to make good decisions. Even if I do become the Unidumbass, the people I love who would never follow me into that lifestyle.
I actually have a formal methodology for how I engage with software/hardware from a FOSS perspective:
Embrace, Subvert, Accept.
For any task I do currently or want to do, I apply this process:
I first try to find and use any FOSS software/hardware that does that thing well enough to use entirely. (Embrace)
If there isn't a FOSS solution that exists or does essential things I need, then I use a proprietary technology in a subversive way to do it. So cracked copies, jail broken or otherwise hacked hardware, or using the proprietary service through an unofficial/unapproved 3rd party app. (Subvert)
If I can't do that either, but the task/need is absolutely critical, only then do I accept using proprietary and unmodified software/hardware. (Accept)
This method has worked pretty great for me. Now about 3 years after starting my FOSS journey, I have almost no software/hardware I use that is in that third category. Basically everything I use is FOSS, hacked, cracked, modded, or runs on platforms that are, and I enjoy tech and computing more than I ever have :)
This is a good method. It is our duty to do everything we can to live by our principles, and be careful about the compromises we make. The more I go deep into FOSS, the more I discover. So much exists, it just takes some work on our part to fit it to our needs. Programming competency does not have to be high, just enough to fix any compile errors.
Yes, I still run my own email server. It is not for the faint of heart, but once it's configured and your IP reputation is clean, it's mostly smooth sailing. I have not had any deliverability problems to date, initial setup/learning period notwithstanding.
If you're not scared away yet, here are some specific challenges you'll face:
Can't recommend this enough: https://github.com/docker-mailserver/docker-mailserver
Despite my willingness to self-host almost everything, e-mail remains the last frontier for me. Keeping abreast of standards, keeping up today, avoiding implications in abuse and many, many smaller issues abound ... and that's despite my fixed IP and ISP willing to set up a reverse-DNS for me.
Instead I've gone with a paid email provider that I'm REALLY happy with.
I originally did but the maintenance burden was killing me. Then last year Proton unified their subscription with VPN and Mail (also upgrading my Proton VPN only subscription to Proton plus) and from there I decided to just go all in on Proton mail. I integrated my domain to Proton mail and never looked back.
No. But I did consider it. Multiple times.
Why not? I'm too scared! Email is the one service that let's an attacker nuke each and everything. It's still the most central/crucial service that almost any service relies on. If I lose access to my mail account, I lose access to pretty much every service.
As much as I would like to host this myself, I simply do not feel comfortable to do it.
Pretty much for this reason for me as well.
I'm a tech hobbyist and I've run/currently run things like Nextcloud, Jitsi, Matrix, XMPP, etc. But all that seems pretty small-scale. However with e-mail, nearly everything relies on it, and from the headaches I've heard about from those who self-host e-mail, it just seems like a perfect way to screw yourself over 😅
AAAHHH!. Now I am scared too.
So much to consider it is dizzying.
I've been hosting my own mail server, ever since I got into Linux. Most companies where I worked before, used self hosted email.
I've since migrated to using mailcow, which takes a lot of the headache out of it.
When you first start, it's a bit daunting. But easily manageble, once you've gained some experience.
I do host my own mailserver for multiple years now without any issues.
I'm using https://docker-mailserver.github.io/docker-mailserver/latest/ on a rented server, not at home. I recently added DKIM and I check my setup via https://mxtoolbox.com and the like in irregular intervals to see if I can improve something.
The only downside I see is spam filtering, which obviously works better with GMail if the whole world population does the filtering for you. But the included SpamAssassin setup does work and catches most of the spam. I do check for false positives/negatives very regularly and have training folders set up so I can easily move messages into the SA training.
I use Cloudflares email routing.
Point my domains name servers to Cloudflares and enable email routing. I can then create any email address in that domain and have it forward to any of my email addresses. Works great when signing up for accounts. The only thing you can't do is fire off email FROM said email address
Edit: can to can't
Wow, didn't know this. I already have my ns pointed to cloudflare, i didn't get it though - we can only send emails?
I used to run my own mail server many, many years ago (early 2000s), but today it's a lot more difficult. I personally don't think it's worth it, but I do have my own domain that I can host anywhere I choose. At the moment, I'm using Fastmail. Lots of nice features, and no complaints.
It's bad out there when it comes to hosting your own email server. This blog post shows somebody's experience in detail, and it's worth reading. https://cfenollosa.com/blog/after-self-hosting-my-email-for-twenty-three-years-i-have-thrown-in-the-towel-the-oligopoly-has-won.html
It's all so sad.
That was a sobering read. We all feel victorious when we see big tech fail after they wronged their users, but fundamental technologies that actually run the world have already been lost, and may never be recoverable for egalitarian use.
I setup my own email server, it was an absolute pain to setup, especially since I had no idea about all the little details of sending and receiving email. It was kind of fun to see everything come together
In the beginning I had a ton of email go into spam boxes, especially with gmail. Later I found out that if you don't add the proper email headers like to: "Name Of Recipient" <email@example.com> it goes straight to the spam folder. (So you always need to provide a name)
I am afraid to touch anything now though, as it is currently very really stable (on a vpn btw)
Not worth the hassle - best compromise is to get your own domain but use a provider like fastmail to host it.
If they turn sour you can move your domain to another mail host.
I've been self-hosting e-mail for over 15 years and hope to continue doing so. Although it's being made increasingly difficult by big tech players. I wrote about it here: https://proycon.anaproy.nl/posts/rant-against-centralising-e-mail/
Great post!
I'm a rather dismayed to see those universities and institutes nowadays no longer as pioneers and innovators in this area, but instead as mere consumers of ready-made corporate solutions, following corporate interests and centralising solutions. I have two employers, both academic, and both have resorted to big-tech corporations that offer solutions like e-mail as a service.
Same here, my university recently switched from their Horde webmail to Exchange. The new outlook webmail is absolutely awful and I couldn't set up all the filters that I had before. Luckily I could enable IMAP login, thankfully without OAuth because imo that's another awful practice, so I can connect to it with non braindead mail clients. Still a massive downgrade and I bet they now have to run it on a 10x as powerful server because I hear Exchange is an absolute monster in terms of resource usage.
(Also, I've been self-hosting mail for probably 4 years at this point. Here's to many more!)
It’s a great learning exercise but challenging to get right and ensure your deliverability and basically impossible from a residential-grade IP address (if you have a business class static IP at home you could pull it off).
I ran an email server for decades but gave in and pay to host my email now.
If google decides you’re a bad guy it’s such a pain to crawl back from that and I prefer my email to just work.
I've been running the families mail server for over 6 years now. I'm using mailinabox.email scripts to setup and manage the server.
I've not had any problems (touch wood) with email delivery. You may have issues if your domain is new, it can take a few days for the big guys to accept email from you.
I say go for it, I think too many are worried about deliverbility and that just causes more centralisation.
Good point. I am really getting pulled down to taking the easy route due to all the complexity and discouragement which is draining my initial motivation, as well as my own laziness settling in on one more thing I can just pay for.
You are right, the fight is not over. I can do my part to decentralize.
E-mail was the first "thing" that got me off of Google (to Proton & then currently Tutanota) but is really the last remaining service I not have self hosted.
I have always read about how difficult and time consuimg it was to run your own mail server, but I felt like I needed to experience it myself. So I purchased another domain and followed the instructions on https://mailinabox.email/.
I am using a small VPS on Hetzner and I have to say the experience has been almost flawless so far. I did need to have my new domain taken off the Domain Block List, but Hetzner gave me a clean IP and defaults to blocking port 25 outbound to prevent spam (simple ticket to open, once account is 30 days old and paid).
I know I'm still early into this journey so far, but it has been really simple and I plan to test this secondary domain for a few months before moving onto it full time.
As an avid self hosted of literally everything else, I can say it has been a lot of fun learning so far!
Yes, and I love it.
I use mailjet as a proxy on outgoing emails so that I get fewer of my sent messages rejected, which works.
It was a pain to setup but it's treating me very well.
Hello, I'm selfhosting mailserver with mailcow in docker container. Its easy to setup. I have static IPv4 and domain. Thats all.
I used to, I don't any more. All the other comments are right, spam is a huge issue, and you can get blacklisted for no reason without recourse. I'm personally using migadu.com, which gives me some of the flexibility of running my own server without the hassle.
I did but I stopped. My server had everything set up (DKIM, DMARC, SPF, Spam filtering) but I gave up after some providers wanted me to jump through hoops to get my mail delivered. Also I never had enough outgoing mail to build some reputation.
That sucks. I don't even know what to think anymore. It is crazy that anyone with our email address essentially has access to when they use giant corporate services like google of microsoft, but every independent server is a bad actor until proven reputable.
I can't be asking everyone I want to email to put me on a whitelist. They'll just tell me to lose their address.
I run my own email server using Mailcow. It works well.
However, I do not even attempt to directly send outbound email. It's very difficult to get your server trusted by the major providers, especially Microsoft (who are very picky about email servers). I have an account with MXRoute (which is an email provider) but only use it for outbound relaying. Inbound emails go directly to my server.
For what it's worth, MXRoute is a great provider to consider if you want to move away from the large ones (Google, Microsoft, etc) but don't want to self-host.
Just take a look at https://docs.mailcow.email/
This runs from a small box with everything included. It gives you all the tools and config needed for running a secure and feature rich email service. Webmail, some sort of exchange emulation, webcalender on top of a solid postfix/dovecot install with rspamd as spam filter. Everything is configurable via a nice web UI.
After 15y running my own mail service and editing a lot of config files, I use this piece of free and open software and find it very good. All you need is a box somewhere in the internet. Running from a homelab will instantly fail, expect you have a static ip.
a bit late to the party here, but I didnt see iRedmail mentioned. been using this to host my own email on a VPS for a little over a year now and its great. for me its worth, you can absolutely make it secure, and its not stupid to run it off a local computer. unfortunately most ISPs make it insanely difficult to host on your home network.
I used to run my own using Modoboa. I've since switched to mxroute for my email.
Very interesting. Thanks for the follow up.
