Maybe you are missing an include?

We have:

```
require "fileinto";
require "mailbox";
require "envelope";
require "subaddress";
require "variables";
require "regex";
require "editheader";
require "include";

```

In dovecot.conf* i found no directly related settings. Just the usual 
sieve settings explained here 
https://wiki.dovecot.org/Pigeonhole/Sieve/Configuration

Can you see the Public namespace and the folder in your MUA or via 
telnet?

Are you sure the ACL are correct? Can be that the error message 
„Mailbox doesn't exist“ is misleading and the permissions are not 
correct.

Here you can see how to debug if not already
