dovecot - Oct 2017 - sieve script not executed?

Hello.

I'm trying to set up a vacation autoresponder but up to now, no success.
I'm using dovecot managedsieve to set up the new filter and to my 
understanding it works correctly and it creates in the user's home the 
link .dovecot.sieve that points to sieve/managesieve.sieve

~$ cat .dovecot.sieve
require ["date","relational","vacation"];
# rule:[Vacanza]
if allof (currentdate :zone "+0200" :value "ge"
"date" "2017-09-29",
currentdate :zone "+0200" :value "le" "date"
"2017-10-09")
{
         vacation :days 7 :addresses ["robi at hidden1","robi at
hiden2"]
"eccoci a dopo";
}

Problem is that apparently this filter is completely ignored.. that is, 
when a new email is delivered to those addresses, no autoresponse is 
sent back to the sender.

I also, followed the troubleshooting guide here: 
https://wiki2.dovecot.org/Pigeonhole/ManageSieve/Troubleshooting and 
everything works as expected.

What is the problem? What am I missing?

Thank you and best regards.
Roberto

You are not loading sieve plugin in your mail_plugins setting.
