Does INBOX/Junk already exists?

Yes, (but empty):

find /var/vmail/hotelsangiorgioriccione.com/info/ |grep INBOX /var/vmail/hotelsangiorgioriccione.com/info/Maildir/.INBOX /var/vmail/hotelsangiorgioriccione.com/info/Maildir/.INBOX/Trash /var/vmail/hotelsangiorgioriccione.com/info/Maildir/.INBOX/Trash/new /var/vmail/hotelsangiorgioriccione.com/info/Maildir/.INBOX/Trash/tmp /var/vmail/hotelsangiorgioriccione.com/info/Maildir/.INBOX/Trash/cur /var/vmail/hotelsangiorgioriccione.com/info/Maildir/.INBOX/Trash/maildirfolder /var/vmail/hotelsangiorgioriccione.com/info/Maildir/.INBOX/Trash/dovecot.index.log /var/vmail/hotelsangiorgioriccione.com/info/Maildir/.INBOX/Junk /var/vmail/hotelsangiorgioriccione.com/info/Maildir/.INBOX/Junk/new /var/vmail/hotelsangiorgioriccione.com/info/Maildir/.INBOX/Junk/tmp /var/vmail/hotelsangiorgioriccione.com/info/Maildir/.INBOX/Junk/cur /var/vmail/hotelsangiorgioriccione.com/info/Maildir/.INBOX/Junk/maildirfolder /var/vmail/hotelsangiorgioriccione.com/info/Maildir/.INBOX/Junk/dovecot.index.log

and same for other v-user "booking"

What's in your ACL file?

cat /etc/dovecot/dovecot-acl

• user=booking@hotelsangiorgioriccione.com lrwsi
• user=info@hotelsangiorgioriccione.com lrwsi

What does these commands return? doveadm acl debug -u info@hotelsangiorgioriccione.com INBOX doveadm acl debug -u info@hotelsangiorgioriccione.com INBOX/Junk
