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

Project mention: postale.io? Is this legit? Email hosting unlimited domains. | /r/webhosting | 2023-06-17
postale.io has an MX record that points to mail.postale.io, which resolves to an AWS IP address (probably an EC2 instance) and has Haraka listening on port 25 (if its SMTP banner can be believed)

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

Yeah thanks for this, I’ve been using it for years! Recently switched to mailslurper:
-
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.
