sieve scripts not work

[CARLOS.TOLEDO at telefonica.net]

Hello, I'm working with cyrus imapd and I need  to implement vacation 
mails. I  have probed with sieve, everything seems to work, but when I 
put the scripts nothing happens. This is one of the
scripts that I probed (v2 script) .

  require ["reject","fileinto"];
  if address :is :all "From" "sarek32 at xxxx.xxx.xx"     {
          reject "testing";
 }


telnet localhost 2000...
    Connected to localhost.
    Escape character is '^]'.
    "IMPLEMENTATION" "Cyrus timsieved v1.0.0"
    "SASL" "PLAIN LOGIN DIGEST-MD5 CRAM-MD5"
    "SIEVE" "fileinto reject envelope vacation imapflags notify 
subaddress regex"
    OK


[root at V root]# installsieve -l -u cyrus localhost
Please enter your password:
vacation.sieve
prueba.sieve
v2.sieve  <- active script
prueba

My imapd.conf  file:
configdirectory: /var/imap
partition-default: /var/spool/imap
admins: cyrus
allowanonymouslogin: no
admins: cyrus
sasl_pwcheck_method: sasldb
sieveusehomedir: false
sendmail: /usr/lib/sendmail

Any sugestion?

thanks in advance.
