Selfhosted

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:

• SMTP ports are typically blocked by many providers as a spam prevention measure. Hosting on a residential connection is often a complete non-starter and is becoming more difficult on business class connections as well (at least in the US, anyway).
• If you plan to host in a VPS, good luck getting a clean IPv4 address. Most are on one or more public blacklists and likely several company-specific ones (cough Microsoft cough). I spent about 2 weeks getting my new VPS's IP reputation cleaned up before I migrated from the old VPS.
• Uptime: You need to have a reliable hosting solution with minimal power/server/network downtime.
• Learning Curve: Email is not just one technology; it's several that work together. So in a very basic email server, you will have Postfix as your MTA, Dovecot as your MDA, some kind of spam detection and filtering (e.g. SpamAssassin), some kind of antivirus to scan messages/attachments (e.g. Clamd), message signing (DKIM), user administration/management, webmail, etc. You'll need to get all of these configured and operating in harmony.
• Spam prevention standards: You'll need to know how to work with DNS and create/manage all of the appropriate records on your domain (MX, SPF, DMARC, DKIM records, etc). All of these are pretty much required in 2023 in order for messages from your server to reach your recipient.
• Keeping your IP reputation clean: This is an ongoing challenge if you host for a lot of people. It can only take one or two compromised accounts to send a LOT of spam and land your IP/IP block on a blacklist.
• Keeping up with new standards: When I set my mail server up, DMARC and DKIM weren't required by most recipient servers. Around 2016, I had to bolt on OpenDKIM to my email stack otherwise my messages ended up in the recipient's spam folder. -Contingency Plan: One day you may just wake up and decide it's too much to keep managing your own email server. I'm not there yet, but I've already got a plan in place to let a bigger player take over when the time comes.

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.

Can't recommend this enough: https://github.com/docker-mailserver/docker-mailserver

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.

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'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 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 protected]> 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)

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.

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

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 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'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/

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.

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.

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 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.

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!

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.

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.

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.

Only people who hate themselves

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.

@DidacticDumbass
Yes I run my own mailserver. I have done it for the last 15 years or so.

I'm also running my own Friendica instance.
