Stalwart is an open source mail server that combines SMTP, IMAP and JMAP with spam filtering, DKIM signing and SPF, DMARC and ARC verification in a single Rust binary. It provides a complete private email platform with a built in web admin console.
The cloudimg image is hardened and fully patched with Stalwart served behind nginx and no shared credentials, since a per instance administrator password and TLS key are generated on first boot. The RocksDB mail store sits on its own resizable data disk, and 24/7 cloudimg support covers DNS, DKIM and TLS setup.
