Since Dovecot 2.4 is dropping replication, I'll definitely need to rework my mail servers and those for BSDMail. I think I'll be going back to Cyrus, which I last used over 20 years ago. The problem is my memories have long faded, so it'll be like studying it again from scratch. And that makes me happy, because it'll be like learning something totally new!

Special thanks to @h3artbl33d for the heads up!

Die Domains "klimail.de" & "klima-mail.de" suchen ein neues, #klimafreundlich|es Zuhause. Das alte Projekt wird leider beendet, wir würden uns freuen, wenn sie anderweitig im Sinne des #Klimaschutz|es weiterentwickelt werden könnten. Die Domains können einzeln oder zusammen übernommen werden, schreibt uns einfach, was ihr damit machen möchtet.

Eigener #Mailserver mit #Stalwart.

Einen #Mailserver mit allem Drum und Dran aufzusetzen ist wahrlich nichts, was man eben mal so nebenher macht. Man merkt, dass die in die Jahre gekommenen Mailprotokolle durch zusätzliche Mechanismen nachträglich abgesichert wurden. Das schlägt sich in zusätzlichen Konfigurationsschritten nieder.

This weekend's project:
Replaced my #Postfix #MTA #mailserver with a new one. I had been running a #Ubuntu based one since 2020, and it didn't deal well with an in-place upgrade.

New machine set up on #Debian 12, with a bunch of tips stolen from @mwl 's book Run Your Own Mail Server and from https://workaround.org/ispmail-bookworm/

If anyone out there runs a #Plesk server, check to see if your have a ton of emails stuck in your mail queue. There was a problematic email security update that got applied within the past 12 hours that caused mail queues to stop processing both incoming and outgoing email.

Fortunately, it's an easy fix.

So, last night I finally took the last step and switchted my DNS entries to my own self hosted mail server (@mwl your book was really helpful - great work!)

But now I am back to my previous problem - which mail client to use on iOS and macOS - any suggestions fediverse? (boosts are quiet welcome)

I'm helping a friend with his mail server, and thinking of hosting my own again. Has anyone tried #mox #mailserver? https://www.xmox.nl looks made for the demographic (like me) who gave up on running their own, but understand that a protocol only stays distributed when enough parties run it.

Der eine Euro monatlich für ein @mailbox_org "Lite" E-Mail Konto ist seit ca 10 Jahren eins der besten Abos, die ich tätige.

Der Service funktioniert nicht nur super zuverlässig, sondern Mailbox.org hat die absolute Inhouse-Erfahrung mit Mailservern - das sieht man immer wieder an Slides, die durch das Internet geistern oder Präsentationen auf den hiesigen FOSS Veranstaltungen. Was ich sagen will: Man fühlt sich gut aufgehoben.

Kürzlich hat Lastschrift bei mir nicht funktioniert, aber kein Problem: Man hat mich freundlich (nicht vorwurfsvoll!) kontaktiert, mir einen Monat Laufzeit geschenkt und gebeten, die Bankdaten zu fixen.

Right now I'm torn between self hosting my mails again and not.
The idea of having full control over my mails is nice - and I know that once everything is up, the maintenance is doable - however there is a second side to the mail server - the client.
How can one be sure of that?
Especially with all the AI nonsense - you have no idea where your mails go.
Thunderbird migh be a solution - but there is no iOS version of that right now - so what to do...

Every four minutes a mail server in Romania connects to my mail server. My mail server then goes to the trouble of doing several online DNS lookups and determines that this is a spammer, and then kills the connection. Four minutes later the Romanian server tries again.

Checking up on the IP address suggests that it would attempt to a brute force attack on username and passwords, if it ever got that far.

Haven't these people got better things to do? I shouldn't be surprised, having run my own home mail server for over twenty years, but even so, the persistent nature of this one is quite annoying. I might see if I can add tarpitting to my Mailcow installation.
