As far I understand an attacker could reconstruct the message from the
index, so one question is whether the extra complexity in notmuch is
worth the minimal extra security over decrypting on delivery and storing
plaintext on the (presumably encrypted) disk. Of course decrypting on
delivery may be inconvenient (or impossible). I have CCed the two people
who have implemented most of the crypto related stuff in notmuch so they
can comment.
