This works as expected for the first time. But later on, also older messages/ threads are included until I delete the virtual/.week/dovecot.index*.
I know there are problems related to this with INTHREAD, but they aren't very easy to solve and for now I've more important things to do.. If it seemed to work before, it was due to luck or due to some bug causing an unnecessary index rebuild. You could set :INDEX=MEMORY to work around this, but I don't know how much worse the performance would become. Or you could just manually delete the virtual indexes once a week. Situation with latest 2.1 is unchanged. But maybe it's easier to fix/ enhance now? Any estimate how much effort it would be?
Just about the same amount of work I think. I haven't really looked at virtual plugin for a while, so I can't easily say how much work it would be. But my guess is that it wouldn't be easy.
