Sieve doesn't work

[dimon]

Hi,

I just installed Cyrus-IMAPD 2.2a (from FreeBSD ports collection) on a new 
server (FreeBSD 4.8) and can't get sieve to work

I have a simple script

require ["vacation", "reject"];

# Vacation Message
if not exists ["List-Id", "List-Post", "List-Subscribe", "List-
Unsubscribe", "List-Archive", "List-Help"]  { 
    vacation :days 7 :addresses "[EMAIL PROTECTED]" :subject "Test 
Vacation" "Just testing";
} 

# Test Sieve
if header :comparator "i;ascii-casemap" :contains "From" "Dmitry Sorokin "  { 
    reject "Test Sieve";
    stop;
} 
 
But nothing happens when mail gets delivered. I don't see any errors in my log 
files. In message headers I see X-Sieve: CMU Sieve 2.2
That means the message was filtered by Sieve, but the rules didn't work for 
some reason. 
The script is activated.

Any ideas?

Best regards,
Dmitry
