Many thanks to everyone who responded to this question. Yes, it seems pretty safe to assume that this (not reconstructing mail folders that don't contain explicit messages) is a bug; but then why doesn't
cyrreconstruct -m work? I can't imagine why this would be that more complicated to implement than `cyrreconstruct -r user.username`; after all, it's only moving one level up in the mailbox hierarchy. In any case, I didn't try copying a message into the offending folder and then running reconstruct again, as this worked: (The mail folder containing folders but no explicit messages is called "Professional".) cyradm -> cm user.bubba.Professional then, logged in as cyrus: cyrreconstruct -f user.bubba.Professional cyrreconstruct -r user.bubba
