  1. Quick architecture thought: Protecting mail gateways (Postfix/Exim) at the application layer during brute-force waves kills your CPU.

    Better approach: Feed rogue IPs dynamically into a Redis-backed ipset at the kernel level.

    Dropping packets at the firewall boundary keeps the application responsive and CPU <1%. It's a virtual infrastructure patch. πŸ§πŸ›‘οΈ

  10. @fluepke Okay. Stimmt, das erschwert es zusΓ€tzlich.

    FΓΌr die TLS Konfigurationen kommt man locker auf sogar 25 Millionen EinstellmΓΆglichkeiten.

    Ich wollte es immer mal nachzΓ€hlen, aber es sind bestimmt 97 Millionen EinstellmΓΆglichkeiten //nur fΓΌr #postfix auf dem #mailserver.

    Dabei geht es doch [eigentlich] nur um Mail raus/rein.
    // anwendersicht

    //admin fluch

  11. Ich habe keine #mailcow am laufen [ist sehr cool, aber ich hatte noch keine zeit zum ausprobieren].

    Meine #mailserver laufen alle seit ΓΌber einer Dekade mit #postfix und #dovecot unter #debian.

  36. 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.
