[Dovecot] Autocreation of sieve filters

Hello,

Is there any way to create a predefined sieve filters during mailbox 

autocreation?

What I want is that my user's mailboxes are automatically created 

(using mailbox option in namespaces) but I want them to have a predefined sieve script.

Using a postlogin script could be an idea, but I'd prefer an automatic 

one, because postlogin only will filter after first user login
