You thought you did what? If you reply on HyperKitty there's no context unless you explicitly quote it.
Ed Greshko:
Lucky for me T-Bird sorts threads based on subject as well as header information. Doesn't Evolution?
It does. I'm using it.
Though he's right that replies should give an unmistakeable clue about what's being replied to. It makes it far easier to understand if you don't have to find a prior message to understand it. And some people delete old messages, especially when they're inundated with hundreds each day.
On Evolution, I have it only showing the last 5 day's worth. If it were easily customisable, I might narrow it down to 3 day's worth.
Back when I did usenet using Forte Agent, I recall doing something similar, with it auto-deleting cached messages that were a couple of weeks old. At least with usenet, you could very easily re-fetch an older uncached message (you still saw the headers, you just didn't have any cached body content for them).
