I am running MS 4-23-11 and SpamAssassin 2.55 release. In "spam.assissin.prefs.conf" I have set "score RCVD_IN_BL_SPAMCOP_NET 4". It never does the bl.spamcop.net blacklist tests. I receive many spams that slip through with a score under 5 and the source IP is listed in Spamcop and has been listed for some time. Any idea what is wrong? Matt
