I tried to remove the "References" and "In-Reply-To" headers of the offending mail, and reindex the thread. This seems not enough to convince notmuch that these mails are no longer related, because the original and separated thread still end up with the same thread ID. Can this be done? Thanks, Ico -- :wq ^X^Cy^K^X^C^C^C^C
