[Dovecot] dovecot.sieve file location?

CentOS 5.2 Postfix-2.3.3 Dovecot-1.1.1 Dovecot.Sieve-1.1.5

I have setup with:

home_mailbox = Maildir/ (/etc/postfix/main.cf) &

mail-location = maildir:~/Maildir (/etc/dovecot.conf)

I have created a 'test' user to test Sieve 'Vacation' setup. My questions are:

1. Which folder '.dovecot.sieve' script is copied into? Is it 'home/test' -or- 'home/test/Maildir' or someplace else?

2. '.dovecot.sieve' script parameter ":days 1" means that the reply is sent once a day. Is it possible to send the reply 'immediately'?
