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.

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.
-
InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
-
I've been running mailcow [1] on a Hetzner cloud server for a few years and am pretty happy with it.
-
Third, Send-MailMessage has been deprecated. Try MailKit instead. To be honest, though, I'm yet to find time and test it myself.

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.
-
Project mention: Stalwart mail server (self-hosted all-in-one mail server) now as an admin webui | news.ycombinator.com | 2024-04-09
It's interesting how there is now
* Maddy: https://github.com/foxcpp/maddy
* Mox: https://github.com/mjl-/mox
* and Stalwart
which all see to aim for more or less the same niche. I wonder if we'll see two of those merge eventually.
-
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.
-
-
ImapSync
Imapsync is an IMAP transfers tool. The purpose of imapsync is to migrate IMAP accounts or to backup IMAP accounts. IMAP is one of the three current standard protocols to access mailboxes, the two others are POP3 and HTTP with webmails, webmails are often tied to an IMAP server. Upstream website is
You see this https://imapsync.lamiral.info/ ? It's only for mails but it's a great solution.

Project mention: Show HN: Inbox Zero – open-source email assistant | news.ycombinator.com | 2023-12-29
https://github.com/neomutt/neomutt is a mature project with similar functionality in its arsenal via tagging and vim bindings, not limited to gmail either. You can also write emails in vim/$EDITOR fluidly.
-
Project mention: Happy 20th Anniversary, Gmail. I'm Sorry I'm Leaving You | news.ycombinator.com | 2024-04-15
* [1] should be https://stalw.art
It's a neat project though, that I hadn't heard of before. I have ran Postfix to do domain-wide email forwarding (to Gmail coincidentally) but going the other way around and having the end destination be self hosted is on my to-do list.

magma
The magma server daemon, is an encrypted email system with support for SMTP, POP, IMAP, HTTP and MOLTEN,. Additional support for DMTP and DMAP is currently in active development. (by lavabit)

Project mention: How to get CardBook in Thunderbird to sync contacts with CardDAV or other type of connection? | /r/ProtonMail | 2023-04-27
-
Project mention: Taking (Back?) My Internet Privacy and Presence | news.ycombinator.com | 2024-01-05
Personally, I use https://github.com/joeyates/imap-backup to archive all my emails and then only keep them on the remote server for as long as I need to (basically until I read them and respond or download an attachment into https://docs.paperless-ngx.com )

Project mention: My collection of Ansible roles for self-hosting everything with Rocky Linux and FreeIPA | /r/selfhosted | 2023-06-02
Mail server using Postfix, Dovecot, and Rspamd
-
Project mention: Show HN: Swift Mail, a native macOS app for JMAP mail | news.ycombinator.com | 2024-02-13
James (https://james.apache.org) has good support too. Only the filter part of the API lacks some features.
-
To add to this, it's reasonably easy to run, and has many different plugins, from a calendar and contacts list, to an online document editor (like Google Docs, except it can be pretty slow and/or resource intensive: https://nextcloud.com/office/), to a simple clone of Slack (https://nextcloud.com/talk/), a mail client (https://apps.nextcloud.com/apps/mail) and other things.
That said, I've had updates (across major versions) break things on multiple occasions, one out of two servers running the exact same version has random crashes and in addition to that the file locking by default (if enabled, but not using Redis: https://docs.nextcloud.com/server/latest/admin_manual/config...) has broken and prevents me from deleting a file that just sits there and takes up a few GB of space. Oh and their Android app fails to upload files if I use the share option, instead of the file picker from within the app.
On the other hand, sure beats storing data on third party clouds and is free, so I'll still keep using it.
