Top 23 Mail Open-Source Projects

Mailspring
:love_letter: A beautiful, fast and fully open source mail client for Mac, Windows and Linux.
I fully agree, moreover this:
> Rolling release distributions like OpenSUSE Tumbleweed follow upstream much more closely while still maintaining stability through thorough automated testing
Shows the author hasn't used Tumbleweed for any reasonable amount of time himself[0][1][2]. I daily drove it for a short while before moving to Fedora.

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.

docker-mailserver
Production-ready fullstack but simple mail server (SMTP, IMAP, LDAP, Antispam, Antivirus, etc.) running inside a container.
I can recommend Docker mailserver (it also works with Podman). It is already pretty lightweight but you can even make it lighter and it has an active community as well as regular updates.

I've been running mailcow [1] on a Hetzner cloud server for a few years and am pretty happy with it.

Project mention: Preview emails with letter_opener, MailCatcher and MailHog | news.ycombinator.com | 2023-08-13
hey HN, I recently published an article going deep into email previewing (in Ruby on Rails, but I think it's relevant beyond Rails).
MailCatcher (https://github.com/sj26/mailcatcher) and MailHog (https://github.com/mailhog/MailHog) are super handy and easy to run locally. Both spin up an SMTP server which you can direct mail to, and give you a nice web interface to browse mail and preview it.
Happy to answer any question! thanks, harrison

Third, Send-MailMessage has been deprecated. Try MailKit instead. To be honest, though, I'm yet to find time and test it myself.
-
WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
-
Project mention: Roundcube and docker-mailserver (Docker Mailserver) on the same VPS | /r/selfhosted | 2023-12-06
Consider installing Mailu instead, which is a single Docker container with a full mail server and Roundcube on top. Very easy to install.
