Trying to do antispam with Sieve

[Adi Pircalabu]

Hi,

Using https://wiki.dovecot.org/HowTo/AntispamWithSieve I'm trying to 
execute scripts when moving to/from Spam folder, however nothing's 
happening. The actions are:
1. Move to Spam: redirect :copy "spamcop_spam at domain.local";
2. Move from Spam: redirect :copy "spamcop_ham at domain.local";

Here's the configuration I'm working with:
doveconf: Warning: service anvil { client_limit=1000 } is lower than 
required under max. load (1153)
# Pigeonhole version 0.4.16 (fed8554)

/usr/lib64/dovecot/sieve/report-spam.sieve contains:
require ["vnd.dovecot.pipe", "copy", "imapsieve", "environment", 
"variables"];
redirect :copy "spamcop_spam at domain.local";
/usr/lib64/dovecot/sieve/report-ham.sieve contains:
require ["vnd.dovecot.pipe", "copy", "imapsieve", "environment", 
"variables"];
redirect :copy "spamcop_ham at domain.local";

I must be missing something obvious. Thanks,
