Hello all, I have a situation where sometimes I sync a later message. For example, the following happens on times: 1a. sync message 1. 1b. not much new 2a. sync message 3 (which replied to message 2) 2b. not much new 3. sync message 2 (which replied to message 1) 3b. not much new This happens because of my workflow of offlineimap. It takes a long time to sync some folders so often I prefer to skip, but sometimes they contain replies. When I do that, notmuch does not correctly construct the linkages. I think this is understandable and I blame my workflow more than notmuch. notmuch wants to be as fast as possible so when it processes message 2 in step 3b, it does not check message 3 because it already checked message 3 in 2b so I think it skips it. Do I have correct understanding of the situation? Is there a config setting that I can put to ask notmuch to look both ways (even at cost of spending more time)? i.e. I want notmuch in step 3b to search through all previous messages to see if they replied to it. Kind regards, Xu
