  17. Any recommendations for #mail server config (templates/examples)? Goal is to have again a config that should do for another 20 years or so. Would it be wise to change to #postfix, or is cleaning up the #exim config better? Should I start with Debians config and just add options?

  22. How would you handle email addresses/inboxes/aliases for a non-lucrative organization?

    I have a dedicated email server I administrate. So I can create as many inboxes, accounts and aliases I want.

    I want an inbox per official role (like treasury, communication, etc) so if people change at those roles, they still have the whole history of the inbox and exchanges.

    But I also want individual people to be able to have their own inboxes.

    Of course, replying to a message directed at treasury should be sent as treasury, and not the individual.

    Are there some templates or good practice to manage that?

    I was thinking the inbox of roles are just there for history purposes and forwarding to the current individual person handling the role. But when they reply, it will be with the role, and not their individual email address.

    I use postfix and have an ldap to handle authentication and authorization.

  28. Con una recente comunicazione ufficiale, Google ha annunciato la dismissione del fetch POP3 da account esterni in Gmail. Chi utilizzava questa funzione per consolidare più caselle email in Gmail si trova ora a dover migrare verso una soluzione alternativa: l’inoltro automatico (email forwarding) direttamente dal server di posta sorgente.

    Questa guida documenta il processo completo per configurare correttamente l’inoltro da un dominio custom gestito con Postfix e Webmin verso Gmail, risolvendo i problemi di autenticazione SPF/DKIM che causano il blocco con errore 550 5.7.26.

    Il problema: Gmail rifiuta le email inoltrate

    Attivando l’inoltro automatico dal proprio server di posta verso Gmail, si riceve quasi immediatamente un bounce con questo errore:

    text550-5.7.26 Your email has been blocked because the sender is unauthenticated.

    Gmail requires all senders to authenticate with either SPF or DKIM.

    DKIM = did not pass

    SPF [dominio-originale.com] with ip: [IP-del-tuo-server] = did not pass

    La causa è strutturale: quando il server di posta inoltra un messaggio, il mittente nell’envelope (Return-Path) rimane quello originale (es. [email protected]), ma l’IP che effettua la consegna è quello del tuo server. Gmail verifica l’SPF del dominio originale contro l’IP del tuo server — e ovviamente fallisce, perché il tuo server non è autorizzato a inviare per conto di domini terzi.

  32. configuring #VPS that I'd had dormant for a while (was being used for experimental stuff) as proof of concept for #Cloud #VOIP #PBX using #FreePBX and #Asterisk with #Debian12 and the #Sangoma install script.

    TIL: to get #PostFix to work correctly with #IONOS without paying for the commercial System Admin module you *must* install

    >apt install libsasl2-modules

    or else the emails get knocked back with message "no worthy mechs found" which sounds like some kind of robot battle 😁 🤖

    also added a swapfile (VPS doesn't have one normally), knocked off the commercial modules (which I don't use) and managed to get a couple of eztensions and routes working (after some false starts as I'm using an unusual config linking to another virtual #pbx)

  35. So, habe gerade mit den letzten Restarbeiten mein großangelegtes #EDV #Server #Infrastruktur Umzugsprojekt beendet:

    Bei den
    #BlackWeekDeals von #Netcup günstig ein leistungsfähigeres #Webhosting für die #Domains, #Mailpostfächer und #Joomla #Webseiten mit 4,5x so viel #Speicherplatz wie bisher sowie einen #Rootserver mit dedizierten Ressourcen und ebenfalls 3,5 mal mehr Speicherplatz als der bisherige #VPS geschossen ✅

    Alle Domains umgezogen


    Alle Mailkonten umgezogen


    Alle Mailaliase wieder angelegt


    Mailkonten in
    #Thunderbird und #Fairmail eingerichtet ✅

    Alle Webseiten umgezogen und Backup neu eingerichtet


    Rootserver mit
    #LUKS verschlüsseltem #Ubuntu installiert ✅

    #UFW, #Fail2Ban, #Apache2, #PHP, #MariaDB, #Redis, #Postfix, #LetsEncrypt (#Certbot) und #DockerCompose installiert ✅

    Alle Configs vom VPS auf den Rootserver übertragen


    #Nextcloud vom VPS auf den Rootserver umgezogen ✅

    Alle
    #Docker Configs und Datenverzeichnisse für diese #Sharkey #Fediverse #Instanz, #Peertube, #Collabora, #Matrix und Testumgebungen vom VPS auf den Rootserver umgezogen ✅

    Backup neu eingerichtet

  36. Don’t suppose I know anyone who has migrated (recently) from exim to postfix? After 20+ years, I’m getting sick of exim‘s abstruse config and general faffiness and postfix is probably the only workable alternative (given how many special things have been accumulated and must be kept.)

    Suggestions for alternate mail daemons gratefully received if they can be coerced into shenanigans.

    (But not sendmail. I did my time in the sendmail mines and I am not returning.)

  37. Hay unos estudios que periódicamente analizan el software usado por servidores en Internet. En concreto este último dice que #exim se usa en el 56% y #postfix en el 37% de los servidores de correo. Casi nada.
