Comments and Reviews
I recently migrated my Stalwart Mail Server to version 0.16 and, while looking for a modern webmail client, I discovered Bulwark.
The developer has finally built what I consider to be an excellent self-hosted JMAP client for Stalwart. Installation is quick and straightforward, the interface is modern and responsive, multiple languages are supported, and there are already plenty of useful settings and customization options available.
If you've recently upgraded to Stalwart 0.16 and are looking for a webmail client that fully embraces JMAP, Bulwark is definitely worth checking out.
