[exim] spams rejected at RCPT but still delivered?

hello, i encounter a strange problem,
i have the following set in exim.conf:

****************
acl_check_rcpt:

.include /etc/exim/exim-rcpt.conf

accept
********

and exim-rcpt.conf contains one rule that matched like:

deny    message         = Sender claims to have a local address, but is
not authenticated nor relayed (try using SMTP-AUTH!)
        log_message     = Forged Sender address (claims to be local user
[${sender_address}], but isn't authenticated)
        !hosts          = +relay_from_hosts
        !authenticated  = *
        condition       = ${if
match_domain{$sender_address_domain}{+local_domains}}

and in my logs i see it rejected but still delivered..??
