Sieve rule: move to folder and forward

["Muenz, Michael" <m.muenz@xxxxxxxxxxxxxxx>]

Dear list,

I'm using Horde/Ingo for creating sieve rules and have activated a rule 
for Spamassassin moving mails with "X-Spam-Status: Yes" to spamfolder. 
Also, there's a rule to forward every mail to another address. Looks 
like this:

require ["imapflags", "fileinto"];

# Spam
if header :comparator "i;octet" :contains "X-Spam-Status" "Yes"  {
    addflag "\\Seen";
    fileinto "INBOX/Spam";
    removeflag "\\Seen";
}

# Forward
if true {
    redirect "backup@xxxxxxxxx";
    keep;
}


My problem is, when "keep" is called, also the spam, which should be 
moved to "Spam" goes to my inbox again. But when setting "stop" in Spam 
rule, mails detected as spam which aren't, wont be delivered to 
backup@xxxxxxxxxx

Any ideas how to solve this?

Thanks,
Michael
