Modern full-featured mail server for low-maintenance self-hosted email

  Insular email distribution - mail server as Docker images

  

  The scope isn't revolutionary - I've used https://mailu.io/ for years for a few 10s of users, and I really like it. I've heard similar good stories from Mailcow users.

  On a quick skim I couldn't tell what was new relative to these older compose-based solutions but (as co-author of similar solution 10-15 years ago) I'm interested to know!

• Mail-in-a-Box

  Mail-in-a-Box helps individuals take back control of their email by defining a one-click, easy-to-deploy SMTP+everything else server: a mail server in a box.

  

  I've set up my email using Mail-in-a-box [0] and it's worked wonderfully. How does this compare with Mail-in-a-box?

  Also, webmail, calendaring are future features in this product. I wonder how critical are those for people setting up their own email.

  If you are familiar with NixOS, and like to have everything declared in Nix configuration, Simple NixOS Mailserver is very robust and easy to use. Have been using it for ~2 years.

• docker-mailserver

  23 11,813 0.0 Shell

  Production-ready fullstack but simple mail server (SMTP, IMAP, LDAP, Antispam, Antivirus, etc.) running inside a container.

  

  I set up docker-mailserver[0] Monday in ~6 hours, most of which were me trying to be fancy using podman instead of docker and dealing with SELinux. But then again I did choose it over mail-in-a-box for just that level of customization. Obviously I can't tell how reliable it will be in the long run yet, but since it's using the classic Postfix/Dovecot stack I expect it'll be pretty stable

  🕳 bore is a simple CLI tool for making tunnels to localhost

  Wireguard itself can help you out with the task of forwarding traffic or creating an overlay network. There's also ngrok and tailscale for forwarding traffic and doing NAT traversal. Except for wireguard, these are commercial platforms, the open source alternatives I know of, are (respectively):

  I don't think of anyone using this kind of tools for emails, the technical limitations elude my understanding TBH. This comment might be border to off-topic, but I think the tools fill in the niche use-case you just mentioned. Have fun!
