    Not really — they are independent projects, not a fork.

    The visual similarity is likely because both use Material for #MkDocs, a static-site-generator/documentation theme, rather than sharing a codebase.

    docker-mailserver is a separate, configuration-file-based containerized mail stack; #mailcow is a broader multi-container suite with its own admin UI and integrated groupware components.

  3. Have just stumbled upon docker-mailserver.github.io . The website looks very similar to . Is this a fork?

  4. 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.

  20. 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.

  31. 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!

  33. @karsbehr Oh, etwa selbst gehostet? #mailcow kann ich empfehlen, läuft hier in der Family seit Jahren wunderbar. Aber klar: Für Laien natürlich eher nicht praktikabel, leider.

  34. @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.

  45. Have just migrated . I was not entirely happy before due to github.com/mailcow/mailcow-doc , 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.
