  3. maddy

    ✉️ Composable all-in-one mail server.

    I've been using maddy mail server as it's quick and easy to setup for over a year now

  4. docker-mailserver-helm

    Kubernetes Helm chart for docker-mailserver

    I host my email server together with a couple of other things on a small VPS (2 vCores and 2GB) with docker-mailserver. The storage space you need is completely dependant on how much you use your email address, with Gmail you get 15GB so if that's enough 25GB will be fine.

  5. Mailu

    Insular email distribution - mail server as Docker images

    Mailu is pretty solid for personal use and is lighter on memory than Mailcow
