The problem is that for some reason, dovecot is duplicating user mails. In the problem I'm having today, a user has 3833 distinct messages in a mailbox, but 122 of them are duplicated 19866 each, so a search in the folder shows 2228712 messages. A force-resync of the folder doesn't fix anything. What worried me the most is that this problem is appearing very often in my system (once a week at least).
Are you sure it's dovecot who is duplicating emails? I have seen this before (not so many copies, but the same effect) and I've always thought it was a thunderbird thing (in every case I've seen the client was thunderbird, and I think your users also use it).
I've always solved with the thunderbird function to remove duplicates. HTH
