Have you rebuilt the index files?

The simplest and surest way is to stop dovecot, move the index files aside, and restart dovecot.


You could start with just the dovecot.index.cache, but usually it is simpler to just force dovecot to rebuild the indexes.

If this is a persistent problem, then you need to figure out why things are wonky (like, are you storing the indexes and/or mail on a network share?).

If things go badly, replace the index files you moved.

I think that maybe 

# doveadm index -A “*” 

will rebuilt the indexes without stopping dovecot, but I will wait for someone to correct me on that.
