We’re excited to announce the release of Stalwart v0.12, a significant milestone that evolves Stalwart from a powerful mail server into a complete, integrated communication and collaboration platform. This release delivers one of the most anticipated features from our community: native support for calendars, contacts, and file storage—all built directly into the server, with no need for third-party integrations.
Can I use IMAP only for archiving my old emails?
Yes. You can simply not expose SMTP at all and just use the IMAP/JMAP part. Unless you need also JMAP, I am not sure it brings you a lot to the table you wouldn’t also get from a good old dovecot. IMO the big advantage of Stalwart is the all-in-one package it delivers plus the good defaults. It also shines when you want a multi node deployment. For a single node IMAP only it might not be the best choice, in my opinion. But it would work, if you want to.
