  1. Yo se que parezco un ladilla con el servidor de correo, pero realmente tener y configurar un servidor de correo en estos días es algo que la mayoria de los sysadmins le rajan. El correo es un bicho tan noble que siempre va a tener prioridad dentro de los servicion de Undernet, pero es un gran desafío por el spam (el cual nosotros mitigamos con amavis+spamassassin con un modelo bayesiano entrenado), entre otros. Con todo el orgullo tengo que decir que nuestro servidor de correo tiene un puntaje casi perfecto, el unico "warning" es que el servidor DNS esta dentdo de la misma subred... chocolate por la noticia, aparte de eso, es perfecto. Mejor que gmail.com, hotmail.com e incluso que disroot.org (aunque por muy poquito, dado que disroot es un muy buen servidor tambien). En la imagen se ve el score de nuestro servidor y otros 2 más #email #correo #undernet #gmail #hotmail #smtp #dns

  17. Wow that was a long break, I've got very little time to talk here lately, work and life taking over...

    But damn was there some activity on the k3s cluster 😅

    Stalwart is finally up and running, with all of my domain names
    I've tested what happens when the server is down (because outages do happen) and everything was delivered as expected

    And using SMTP2Go to avoid having to maintain an IP reputation

    Chef's kiss
