Хватит строить Kubernetes для пятнадцати человек
Я много лет занимался инфраструктурой. Потом перестал и ушёл в продукт — но привычка заглядывать: «А как у вас тут всё устроено?» осталась. И вот теперь я хожу к клиентам по совсем другим вопросам, а глаза всё равно выпадают.

#aliasvault sieht mit nach einem Upgrade zu #bitwarden / #vaultwarden aus. Das schaue ich mir die nächsten Tage mal an. Bisher lief mein Alias Management immer manuell und ziemlich umstänich ab über meinen Account bei meinem #mailcow Server.

Ich habe hier eine Reihe von #Roundcube Addressbüchern, Signaturen etc, die ich gerne nach #Mailcow umziehen würde. Hat das schon mal wer gemacht?

Viele Funktionen nutzte ich in der Nextcloud ja nicht. Deshalb habe ich mich ja für andere Wege entschieden. Cryptomator und Joplin mit einem S3 Speicher, Kalender und Kontakte nutze ich mit Mailcow.
Jetzt bekam ich vor kurzem auf der Arbeit eine Datei zugeschickt. Zu groß für das Postfach, also per Link um diese bei swissfiles in den nächsten 30 Tagen herunterzuladen. Die eine oder andere Datei hatte ich auch hin und wieder per Nextcloud geteilt. Dies fällt ja aber nun auch weg. Also musste eine Lösung her: Pingvin.
Abgesichert mit Authelia als OIDC und die Registrierung deaktiviert, weil ich ja nicht will, das Gott und die Welt unbekannte Dateien über meinen Server verbreitet. Das kann ja mal schnell nach hinten losgehen. Fehlte nur noch ein Virenscanner, falls ich mal einen Link erstelle, über den andere User auch Dateien für mich hochladen können.
Für mich immer noch sinnvoller als eine Nextcloud zu betreiben und zu warten.

for those running #mailcow, what are some symbols that you've adjusted that made the biggest impact? I'm pretty good at blocking spam, but getting some ham mixed in with spam. Thanks!

@Wolkensteine Well, a self-hosted email server is always uneasy to set up and maintain. You will need a special DNS setup. You will need to constantly monitor and maintain your domain reputation to prevent Google and Apple from marking your mails as spam and so on. I see #Mailcow is a popular choice among those who dared.

Have just migrated #mailcow . I was not entirely happy before due to https://github.com/mailcow/mailcow-dockerized/issues/1245 , now I am even more displeased. After using the official backup and restore procedure, users authentication stopped working. That's pretty disappointing, on top of backup mechanism which is non-incremental, and restore mechanism which requires mailcow to be *running*. I resorted to "rsync /var/lib/docker/volumes/" instead, which worked.

Those running mailcow, how was the spam filtering out of the box? Thanks.

Wtf I had an openrelay for weeks because of this https://community.mailcow.email/d/5370-ipv6-prufung-im-09-update-unzureichend
Everything about this is dumb.
1. why is this ipv6 check so weak?
2. why can't you persist the setting?I only noticed this because of an abuse message from my provider. Very bad way to start the day.

Ich habe keine #mailcow am laufen [ist sehr cool, aber ich hatte noch keine zeit zum ausprobieren].
Meine #mailserver laufen alle seit über einer Dekade mit #postfix und #dovecot unter #debian.
