Copied from r/selfhosted as seems interesting enough to share with wider audience.
I’m excited to announce the release of Stalwart Mail Server, a single binary solution that combines the Stalwart JMAP, Stalwart IMAP, and Stalwart SMTP servers into one easy-to-install package.
In response to user feedback, some key enhancements were made. Stalwart Mail Server now supports LDAP and SQL authentication, providing seamless integration with your existing infrastructure.
For single node setups, RocksDB has been replaced with SQLite with the option of using LiteStream for replication. For larger, distributed setups, support for FoundationDB was added, letting you scale to millions of users without sacrificing performance. Additionally, it is now also possible to store your emails in an S3-compatible storage solution such as MinIO, Amazon S3, or Google Cloud Storage.
Other notable updates include support for disk quota, subaddressing (or plus addressing) and catch-all addresses.

I look forward to your feedback and questions!

What the hell is JMAP anyway? Never heard of Another new alternative to IMAP. Can be read here.
Ok, so JMAP is an E-Mail API, replacing proprietary solutions like Gmail’s(?). But for what? What does it do/solve?
Unfair. JMAP is a official IETF RFC, a working standard powering a very large mail email service, a modern, open move towards a sort of open ActiveSync.
Fastmail has done a lot of work on this, for free, and no one has a better suggestion, so it’s the state of the art.
IMAP is not proprietary. Gmail does support it though, as does pretty much every email provider under the sun. It has limitations though, and JMAP is one proposed alternative to solve some of those.
Note that I don’t have enough knowledge to emit an opinion on whether it’s good or not. I’m just pointing out a couple facts.
It solves a bunch of stuff caused by IMAP being a bit of a mess. Top of the list of JMAP benefits is:
[JMAP] is stateless. It doesn’t need a persistent connection, which is better for mobile use, which may have intermittent network access and where battery life must be conserved by turning the radio off whenever possible.
JMAP was developed by the guys that run FastMail (who are the primary developers of the open source email server Cyrus-IMAP). It’s easier to implement and more performant.
Side note, Cyrus is a pretty amazing mail server. It doesn’t get much love here, but it’s bombproof, fast, supports multi-node clusters, IMAP, NNTP, CalDAV, CardDAV and more that I’m forgetting. It’s just a bit old school as far as configuring goes.
