Yeah, I read about this decision in Trojita a couple of years ago. Understandable. I just didn't know that this was a similar problem. For reference, the IMAP server I'm using is Zimbra. > If you have suggestions on how to better reflect this state in the UI, > please propose them here. Not sure what you mean.

However, I don't see myself actively > working on this. The code that supports this surely exists somewhere. Other clients, incl. Kmail, support this threading. Wouldn't it be possible to reuse it? (I'm not a programmer, so I can't contribute code, unfortunately.) > [1] https://tools.ietf.org/html/rfc5256 > [2] https://tools.ietf.org/html/draft-ietf-morg-inthread-01 -- You are receiving this mail because: You are watching all bug changes.
