  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.

    //aus aktuellem anlass
