[Dovecot] dovecot-lda - sieve notify support

Hi,

does current implementation of dovecot-lda supports sieve script like this:

     require ["notify"];

        if header :contains "from" "boss@example.org" {
            notify :high "This is probably very important";
        }

And if it does, what happens in this case ? Is there any configuration for other notification methods? I didn't notice anything in configuration file.

Thanks, Sebastjan
