Version 1.2.16 was migrated from maildir to dbox about a year ago via the convert-plugin. After previous attempts to "clean" the hybrid maildir-dbox situation I used imapsync to copy all mails from the old account to a new account. I would assume in this case I get a clean dbox-mailmap. I tried to run dsync on this new map but noticed a lot of mails are not syncing:

Hmm. I thought I already answered this. Maybe I got distracted while answering it and aborted..

Anyway, you need a different way to migrate the hybrid maildir. http://dovecot.org/list/dovecot/2010-September/053012.html had some old ideas, but there is a newer program explained in http://dovecot.org/list/dovecot/2010-November/055191.html and the program itself is slightly updated in http://dovecot.org/list/dovecot/2010-November/055192.html. Save the attachment.bin into dbox-dehybrid.c and compile and run it. Get backups. :)
