There is a new fork of paperless-ng called paperless-ngx. I'd appreciate, if you could open a bug report there. If the new fork gets enough traction, I'll submit a PR here to point to the new version.

but it's not a bug, it's just ignoring a dependency restriction on nixpkgs side. requirements and code regarding imap-tools is exactly the same in paperless-ng and paperless-ngx, also there's no pending PR in paperless-ngx that'd make it work with newer versions of imap-tools. Thank's for pointing me to paperless-ngx - the nature of the tool really requires longvivity.

I could create a PR overriding the used imap-tools version - is that the way to go?

ah sorry, I must have overlooked that part.

Yes, I'd think so. At least for now. For the long run, we'd need to update the dependency on paperless.

definitelyseems like that, going by https://github.com/jonaswinkler/paperless-ng/issues/1599 and https://github.com/jonaswinkler/paperless-ng/issues/1632. The paperless-ngx repo has 1.8k stars already at this point, has almost daily active commits by contributors previously active on -ng, and seems to be mostly recognized as the new upstream.

@a7p is this still an issue? Have you tried the paperless-ngx 1.6 version?
