I'll second the suggestion of examining your logs to determine if this is
the case and, if so, how.

In addition to suggestions made by others, make sure that you have the
addresses corresponding to RBL responses included in your local blacklist,
or else the RBL servers won't actually cause SMTP connections to be
rejected. For the RBLs listed above, you need at least:
127.0.0.2-127.0.0.3 ; *.3 for Korean IPs in cn-kr.blackholes.us
127.1.0.1-127.1.0.32 ; opm.blitzed.org
If you want to determine if you are successfully rejecting connections
based on RBL responses, filter your logs for entries containing
'blacklisted per rbl'.
