Sieve script not created

Looking in /var/spool/dovecot/private/domain/user I can’t see for some users “sieve” folder with default.sieve script.

For some users I can see:

-rw-------  1 dovemail dovemail  277 dic 14 09:15 .dovecot.svbin
drwx--S--- 10 dovemail dovemail 4096 dic 14 09:20 Maildir
drwx--S---  3 dovemail dovemail 4096 dic  9 11:16 sieve

For others users I can only see

drwx--S--- 10 dovemail dovemail 4096 dic 14 09:14 Maildir

UCR variable mail/dovecot/sieve/spam is set to YES and mail/antispam/requiredhits to 3.0

What can I do have the sieve script for all users? Is it possible to relaunch the creation script?
