What is Stalwart Mail?
In simple words, Stalwart is an integrated email and collaboration suite for secure and efficient communication.
Unlike any other solution on the market, Stalwart redefines the email server landscape. Traditionally, running a mail and collaboration server meant stitching together multiple outdated components—like MTA, message store, spam filter, calendar, and contacts—each with its own configuration quirks. Stalwart streamlines this into a single, efficient binary with a unified configuration. Built in Rust, a language renowned for memory safety, it delivers a robust, secure foundation for modern communication and collaboration.
How can we help?
We have a long history and experience using various open-source and proprietary e-mail solutions: Sendmail, Qmail, Postfix, CommuniGate, Zimbra/ZCS, etc., and it’s been extremely complicated to keep everything working together, while being up to date with the most recent security patches and comply with the highly unfriendly big-tech. E-mail, as well as the Internet, are meant to be free and decentralized. Over the past years, we have pushed Simple NixOS Mailserver where possible, however, there are still many moving parts and certain fragile areas (DNS and rspamd) as well as it is very challenging to set up any reasonable form of HA or fail-over.
Stalwart addressed all of these, and not just that! It has native observability baked in, it can use various storage backends that enable clustering/HA, and it does not have many moving parts being a single binary – developed in our favourite Rust language.
