Hi Timo, thanks for the patch.
I applied it, compiled doveadm and tried the new binary but it still baily out with this message: dsync(u...@domain.de): Error: Exporting mailbox INBOX.Sent failed: Can't lookup saved-date for UID=515: Internal error occurred. Refer to server log for more information. [2016-01-10 17:02:08] Do you have any idea how I can skip these errors ?
