I upgraded from version 2.0.12.
Running a force-resync on affected mailboxes did resurrect some different and very old mail, but this only happened on first run of force resync. The mail that reappears every day is still happening.
since you are running mdbox did you run purge before the upgrade?
No purges previous to the upgrade. Running them now also seems to have no result.

Recently I upgraded dovecot quite a few major versions. Since then some mailboxes are experiencing deleted mail reappearing. It seems to be happening roughly once a day, but not for every mail client or mailbox, I have at least two clients with this issue: Thunderbird and Outlook
Did you reindex everything? How many versions did you skip?
I do not think the way messages are marked has changed, but I would guess this is an indexing issue.
