@jwildeboer @homelab Well, in my experience, such statements mostly come from people, who install "Exchange" and give up weeks later, because it still does not magically work by itself. Hosting an email server (MTA) demands knowledge, and people who possess such knowledge will have no problem getting that stuff up and working properly. It gives you wild control over who you communicate with though. Priceless.

@jwildeboer @homelab
I'd like to try this. Right after I'm done with renovations :)

@jwildeboer @homelab

Hear hear! i have also been running my own email for about that long. 23 years according to the age of my domain name registration. Started out on a shared hosting server, moved up to a VPS, and for the past decade have been on a dedicated server. (i also use it for a couple of websites, some offsite backup storage, and misc dev work.)

There is a learning period, and i will admit that as someone who has a couple of decades of experience in the webhosting industry am not just an average person, but really the hardest part is the initial setup. After getting the basic server, i set it up to automatically install updates every night and did some basic security hardening, like disabling direct login as root via ssh, but other than that it's pretty hands off. As a small site it's not a target for any specially directed attacks and i've never had a security breach that i know of.

I've been operating a tiny mail (and web) server for my family and friends for 20+ years now, from qmail on a Pentium II in the basement to a postfix/dovecot setup on a tiny VPS, similar to what @jwildeboer set up. I endorse his message whole-heartedly; If you can, roll your own, or find someone in your bubble who can, and setup a mail server for a whole group of people.

I never bothered with high-availability. Never lost an important mail.

Until spammers broke the Internet even harder.

Receiving e-mails works great, but beware of using your own mailserver to send emails. Mails coming from dynamic IPs are typically rejected, which destroyed the true self-hosting aspect for most "normal" people. Also, you must closely monitor your reputation/logs, lest you end up on e. g. T-Online's blacklist for reasons like "no direct contact information deducible from the FQDN", and t-online.de users will not receive your mails.
Running one diligently on a VPS is still worth it, though, if you're aware of the pitfalls!

@jwildeboer @homelab Talk about timing. I got my mail server public yesterday with the only fixing needed for DKIM misconfiguration in rspamd xD
Once I get the PTR set, I should be good to go. Definitively a good learning experience.

@jwildeboer @homelab I’ve run my own email server since forever… it is not as difficult as people think, and it works when setup correctly. Sadly so many people are brain washed into thinking it is impossible or too difficult for a human. Love hearing email server success stories. Hope it convinces even one more person to drop big tech in favour of sovereignty and privacy. I admittedly don’t custom install by hand anymore, though that is certainly doable

@jwildeboer can you send mail to (new) people that use outlook/office365?

@jwildeboer
Running a self hosted mail server properly is hard. I had one running for several years, but when I had to do a new setup, your blog posts really helped a lot 🙂.
@homelab

@jwildeboer @homelab I've done the same since ~2005. The only "hard" part is making sure you're on a reputable hosting provider which isn't regularly listed on the various RBLs.

@jwildeboer @homelab Me too, pretty much the same... My HDD is bigger but then, if I could get my wife and daughter to clear out their inboxes.....

@jwildeboer @homelab do your mails make it to other people's inboxes reliably or do they get flagged as spam by Google/Microsoft/Yahoo?

@jwildeboer @homelab Nice. I've always found it a bit weird that my ISP wants over $100/month for a static IP when I can purchase a virtual server for less than $10/month. That's the only reason why I don't host it at home (anymore).

@jwildeboer @homelab (How) do you do malware checking? Clamav requires more than 2g currently

No webmail, only simple SMTP/IMAP with Postfix and Dovecot. All incoming mails are stored encrypted, all traffic uses TLS with a LetsEncrypt certificate. DKIM, SPF is configured. Admin work consists of keeping the OS and firewall up2date, this means maybe 1-2 hours in total per month. I am not saying you can also do that (I have a lot of experience). But I am saying that those skills can be learned and result in a lot less worries about being reachable :)

#DigitalAutonomy #SelfHost @homelab

@jwildeboer @homelab You are so courageous!

What is your experience with ending up in spam?

Also, the economical cost is quite cheap, but how about maintenance time?

Lastly: have you considered switching to Stalwart by @stalwartlabs?
