Those suggested fixes you found have to do with permissions, but in your case the error is file not found. I would go that direction in trouble shooting. Off the top of my head two things that could hide files from processes are SELINUX and CHROOT. (https://wiki.dovecot.org/Chrooting) But no idea if either of those have to do with your issue.
