[Dovecot] lda sieve error using global after sieve script

[Tim Traver]

Hi all,

ok, so I've implemented an after sieve script with the following line 
in the plugins area :

sieve_after = /home/mailboxes/sieve/to_spam_folder.sieve

It seems to work ok on some accounts, but then I'm getting the following
error in the deliver error log for many accounts :

Error: sieve: script /home/mailboxes/sieve/to_spam_folder.sieve failed
with unsuccessful implicit keep

here is the script :

require ["fileinto"];
# rule:[Spam and Virus Tag]
if anyof (header :contains "Subject" "[VIRUS-TAG]",
        header :contains "Subject" "[SPAM-TAG]")
{
        fileinto "Spam";
        stop;
}

which is a very basic script that files stuff into the spam folder. I've
checked some of the accounts, and the folder is there, and all appears
to be ok...

I'm not sure if its a compiling error or something, and I'm not sure if
that error message means the message didn't even get delivered anywhere.
it sounds like it gets discarded...does it?

any help would be appreciated.
