  • Mailspring

    :love_letter: A beautiful, fast and fully open source mail client for Mac, Windows and Linux.

    Project mention: What Is Wrong with Enterprise Linux | news.ycombinator.com | 2023-07-20

    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.

  • docker-mailserver

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

    Project mention: Alternative to MailCow | /r/selfhosted | 2023-06-04

    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.

  • Mailcow

    Project mention: Ask HN: Self Hosting an Email Server? | news.ycombinator.com | 2024-01-29

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

  • MailCatcher

    Catches mail and serves it through a dream.

    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

  • MailKit

    Project mention: UTF8 encoding in send-mailmessage doesn't work. | /r/PowerShell | 2023-06-09

    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.

  • Mailu

    Insular email distribution - mail server as Docker images

    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.

  • maddy

    Project mention: Exploring Self-Hosted Email Services | news.ycombinator.com | 2023-11-30

    Have you seen our service yet? You might not have since we don't focus on ads/marketing too much; we've been dedicated to high-quality product efforts.

    Our service is called Forward Email (https://forwardemail.net) and it's so easy to use we use it ourselves (dogfood style).

    Although we don't have mail clients yet, we fully support Thunderbird and any other email client (e.g. K-9 Mail, FairEmail, Apple Mail, Outlook, Gmail, etc).

    Our FAQ is extensive at https://forwardemail.net/faq and we walk you through set up, which is tailored to you based off your specific registrar/DNS provider. We also have instructions for SPF/DMARC/DKIM and more, so that you land in the inbox.

    Lastly, unlike everyone else, we're actually 100% open-source on GitHub at https://github.com/forwardemail
