Secure & Modern All-in-One Mail Server (IMAP, JMAP, SMTP) - GitHub - stalwartlabs/mail-server: Secure & Modern All-in-One Mail Server (IMAP, JMAP, SMTP)
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’ll say that I really like this idea. The challenge with self-hosting email will always be in the message deliverability to others because the big bois don’t play well with smaller mail servers and often route legitimate messages to spam. This is even despite implementing SPF, DKIM, and DMARC properly.
