Hello everyone!

Does anyone know good softwares that are available as docker installations for self-hosting a full email services stack.

I heard about mailu, mailcow:dockerized, poste.io and the recent Stalwart that’s been released quite recently.

I tried to install them, and I must say that poste.io seems quite user-friendly, though it seems that it doesn’t allow to redefine the recipient delimiter characters.

Do you happen to know about other tools that could do the same job?

    I use Docker Mailserver . It is pretty lightweight, but it does not come with any fancy GUI for configuration, that is done on the command line mostly.

      @raphael @skbo I use the same, and even if everything is done on CLI/conf file, it just works for me for many years without a problem.
      You can customize pretty much everything (I created “generic” address to give to businesses : [email protected]), since underneath, it’s just plain old postfix.
      I put a rainloop alongside to have a webmail, and can’t be happier.

    I can recommend Mailcow. Been using it for over 2 years without issue.

    Before Mailcow I used mail-in-a-box but that is not dockerized.

    I’m sorry but I don’t have any suggestion about dockerized email server, I just came here to ask you if you’ve fully evaluated to run your own mail server. I’m not saying you shouldn’t, just to be careful. Email server is the one thing that I would never self host, there’s too much at stake, IMHO.

      Thanks for the warning. Believe me, I know how mails can be hard to host, and I would have made the same warning to someone that wants to start self-hosting mails.

      I wanted to update my already installed and already working system and check if something new appeared from the time I installed my server.
