  • maddy

    All-in-one (SMTP, IMAP, DKIM, DMARC, MTA-STS, DANE) email server

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

  • InfluxDB

  • 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.

  • Mailu

    Insular email distribution - mail server as Docker images

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