Sieve can't move messages in a public namespace

[Paolo]

Hello all,
finally I upgraded to dovecot 2.2.10 (that comes with CentOS 7.4).
But the problem is still there!

Why sieve can't move a message in a public namespace complaining about 
"Mailbox does not exists"?
None of you ever try? Some of you have a working setup?

I attach "dovecot -n" output.

The sieve script is:

    require ["fileinto", "envelope", "mailbox"];

    if header :contains ["From"] "AN at ADDRESS.com" {
           fileinto "Cond-UFF_FORNITORI/CONTABILITA/Ricevuta";
    }


The error:

    error: msgid=<5df93e60-676c-f6bb-68b8-c17fe74934d0 at ADDRESS.com>:
    failed to store into mailbox
    'Cond-UFF_FORNITORI/CONTABILITA/Ricevuta': Mailbox doesn't exist:
    Cond-UFF_FORNITORI/CONTABILITA/Ricevuta
