Best minimal Email Server for Linux

• Mail-in-a-Box

  183 13,278 8.8 Python

  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 hace been using Mail-in-a-box for almost 3 years. It's been painless and the set up is done with a single shell script you can download and execute on a clean VPS. It also takes care of all the DNS stuff for you.

• Mailu

  51 5,400 9.4 Python

  Insular email distribution - mail server as Docker images

  

I can recommend Mailu https://mailu.io/

• docker-mailserver

  92 13,292 9.5 Shell

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

  

Have a look at this project: https://github.com/docker-mailserver/docker-mailserver

• emailwiz

  Script that installs/configures a Dovecot, Postfix, Spam Assassin, OpenDKIM Debian web server

• nixos-mailserver

  12 - -

If you have the option to install NixOS (or convert the preinstalled distro), I can recommend Simple NixOS Mailserver. It is a complete solution (postfix, dovecot, rspamd), and can easily be extended with roundcube webmail.

• crowdsec

  169 7,746 9.6 Go

  CrowdSec - the open-source and participative security solution offering crowdsourced protection against malicious IPs and access to the most advanced real-world CTI.

  

I would suggest trying out CrowdSec in favor of fail2ban. It's free and open source, supports postfix(can detect spammers as well) and dovecot. Basically it's a advanced and modern fail2ban utilizing crowd sourced threat intelligence by default meaning that all users anonymously share information about relevant attacks to others users thereby helping each other out.
