@richiekhoo The delay isn’t due to any unwillingness to comply, it’s simply been a matter of prioritization. Over the past few months, the focus was on delivering major features like WebDAV support. That said, I'm still fully committed to resolving the packaging issue because we want Stalwart back in Arch as much as you do.
@ricardo@mastodon.bsd.cafe See this thread https://github.com/stalwartlabs/stalwart/issues/253 - If someone contributes a CI job to compile BSD from a Github runner, it will be officially supported.

@richiekhoo Stalwart can absolutely be compiled without any proprietary code. All you need to do is omit the Enterprise feature flag during compilation, and what you get is a 100% AGPL-3.0 build. The Arch package removal wasn’t because the software suddenly became non-free, but rather due to a packaging requirement: Arch needs a clean separation of the Enterprise code from the source tree, and that’s something we haven’t done yet (it will be implemented as a script).
