You'll need to set UNIX permissions in a way that it works.

Dovecot ACLs won't get you around UNIX permission problems.

No. What that means is that there's probably a bug in the code that
tries to check what permission problem you have (hopefully fixed in
later version, v1.1.10 is getting a bit old). The ACL it mentions isn't
Dovecot ACLs, but filesystem ACLs or perhaps SELinux or something else.
I guess I should change the error message.
