2026 Spring News | An average guy's IT (mis)adventures

Here is where I talk about the stuff I'm doing on my server, things I break, bugs I find and so on.

@chrisn I've used #mailcow on a VPS for the past 6 years and recently I migrated to https://nixos-mailserver.readthedocs.io. So far both have been reliable and didn't need much attention after the initial setup and once the IP was trusted by the big providers.

Wir haben einen #openLDAP Server für die Verwaltung der Nutzer:innen, #Vaultwarden für Credentials, #mailcow für Kalender/Mail sowie #Nextcloud für Filestorage eingerichtet. Office kann jeder MA nehmen was er will solang es keine MS Lizenz benötigt. 🙂

Als Mailclient haben wir uns für #emClient entschieden, für den gibt es aktuell leider keine Version für Linux, ich hoffe das ändert sich irgendwann.

Teams war nie in Verwendung, wir nutzen oldschool mail. :-)

#MailServer #UI #Mailcow

Mailcow is a complete mail server suite that provides a modern Web UI for administration.

@zeitverschreib
Eigene VPS bei @netcup und ein #mailcow sollte alle möglichen (un unmöglichen) Szenarien abdecken ...
How to block yourself from accessing to your #selfhosted #mailcow server:
1. remove an existing mailbox without removing the account definition from your devices
2. wait for netfilter to block your IP range
3. success! no more access to your mails nor the admin interface.
My brain is more and more revolting against the incidental complexity of our IT systems. Today I had to debug an issue with #mailcow’s netfilter which makes me wonder why we need the combined complexity of #debian, #netfilter and especially #docker to send and receive emails. So much time lost that could be better spend otherwise.

To be perfectly honest, #Mailcow continues to impress me. There are countless options for fine-tuning; but once installed and the basic settings configured, it does exactly what it's supposed to. Everything else is just a bonus.

#SMTP, #IMAP, #POP, spam filter, #DKIM signature, webmail with S/MIME capability, #CalDAV, #CardDAV, #SIEVE

Yes, I participated in two projects funded by #NLnet
First, #CAcert (I was on the board from 2012 to 2016, most recently as Vice President). Then, from 2016 until its unfortunate discontinuation in 2022, I worked on the #WPIA project, again as Vice President and also as Managing Director.

I have to say that the email server actually requires the least work of all.
I use the #MailCow Suite @doncow , and a lot of it is already automated, and the individual components work together seamlessly.
My mail server "serves" almost the entire family network, as well as 4 small businesses and a handful of clubs. So, about 10 or 12 "main domains", and around 20 or 25 alias domains.

IP reputation hasn't worried me much either; I've only had one blacklisting issue in the last five years, but the hosting provider resolved it within a few hours. And of course, you have to ensure that #DKIM, #DMARC, #SPF etc. work together correctly. Then it becomes quite easy.
So I'd say things have gotten easier since I started #selfhosting e-Mail years ago. (#mDaemon was my first hosting suite for e-Mail).

Edit: I should also mention that I run an email setup with a primary mail server and a backup mail server.
