Hi,

I'm afraid that with current version there is no solution for this.
There were some proposals to tell notmuch which files you want to index
and use this functionality to run indexing right on delivery on when a
rename is detected (e.g. by inotify). See
id:1264719647-sup-9540 at ben-laptop for details. AFAIK nobody have sent
patches for this yet.

Cheers,
