[ingo] filter does not work

[Andreas Moroder]

Hello,

every day I get reports from the spamfilter of our provider.
The subject of the mail looks lite this

SPAM-Report 28-07-2011: andreas.moroder at sb-brixen.it (0/2/25)


the first number indicates if there are mails that could be recovered 
from the filter.

I would like to creae a Ingo filter that move all the mail that come 
from our provider and have

.it (0/

in the subject to a subfolder and leave all that have a number differnt 
from 0 in my inbox.

I have this filter

# Spam mit 0
   7: if allof ( header :comparator "i;ascii-casemap" :contains "Sender" 
"support.spam at siag.it", header :comparator "i;ascii-casemap" :contains 
"Subject" ".it (0" ) {
   8:     fileinto "INBOX.spam-reports";
   9:     stop;
  10: }

( The subject starts from .it because I have two mail addresses )

Why does this not work ? Is the ( the reason ?

Thanks
Andreas
