Hi! Was looking at your config and I am puzzled why you are adding
mailbox INBOX/Archives { auto = no special_use = \Archive } under namespace 'Synoptic'? Do you actually have a virtual folder config for all those folders? You can't just "move" folders into a namespace by declaring them there, those become Synoptic/INBOX/Archives, and require a dovecot-virtual file to work. If the only mailbox in Synoptic, that has a dovecot-virtual file is 'AKTUELL', you should remove all folders that do not have a dovecot-virtual file under /var/mail/virtual.
