Where is the Maildir coming from? Has it been used by Dovecot earlier, or is it something else?
The maildir is already in use by Dovecot and has received mail. Then we do the conversion in-place to mdbox (or vice versa).

So mdbox apparently didn't exist before you ran dsync.
That's correct. We're changing from the maildir format to the mdbox format in-place.
dsync(blahmail): Debug: brain M: Local mailbox tree: INBOX guid=60f6d91a25fddb5983040000a19766e2 uid_validity=1507589418 uid_next=1 subs=no last_change=0 last_subs=0 dsync(blahmail): Debug: brain S: Local mailbox tree: INBOX guid=e6191d3644fddb59e2040000a19766e2 uid_validity=1507589413 uid_next=2 subs=no last_change=0 last_subs=0
But here the INBOXes already have conflicting UIDVALIDITYs. One of these was created too early.
I think one of these helps:
- disable quota
- disable quota_clone
- disable mailbox_list_index
Disabling mailbox_list_index seems to resolve the issue. Unfortunately though, I'm fairly sure we need that setting though for our environment, but mayhap we can just disable it during the sync. Thank you for the suggestion!
