See my other email (that had potentially private details in it,
the sha1s of some of the user's emails)

I suspect it's just that you have:

expunge_mode: delayed

And you didn't realise that in 2.4.x, the EXPUNGED records are
retained in cyrus.index with a magic flag rather than copied to
a separate cyrus.expunge file.  This means that even though there
are lots of files on the disk, what you're actually doing by
deleting cyrus.index and forcing a full reconstruct is bring BACK
emails which the user has already deleted once!
