More information after enabling mail_debug, in maillog I see:

So imapsieve "sees" the configuration, then I went and enabled debugging 
in the 2 sieve scripts which now read:
1. /usr/lib64/dovecot/sieve/report-spam.sieve
require ["vnd.dovecot.pipe", "copy", "imapsieve", "vnd.dovecot.debug"];
debug_log "/var/tmp/report-spam.sieve.debug";
redirect :copy "spamcop_spam at domain.local";
2. /usr/lib64/dovecot/sieve/report-ham.sieve
require ["vnd.dovecot.pipe", "copy", "imapsieve", "vnd.dovecot.debug"];
debug_log "/var/tmp/report-ham.sieve.debug";
redirect :copy "spamcop_ham at domain.local";

Should I expect to see debugging in /var/tmp/report-ham.sieve.debug and 
/var/tmp/report-spam.sieve.debug, respectively? The 2 files aren't 
created, nothing in that directory.
BTW, getenforce=Disabled.
