It's the default ruleset and it checks only the lastexternal address. See: # /var/lib/spamassassin/3.003001> grep -R RCVD_IN_PBL * updates_spamassassin_org/20_dnsbl_tests.cf:header RCVD_IN_PBL eval:check_rbl('zen-lastexternal', 'zen.spamhaus.org.', '127.0.0.1[01]') But thanks for the hint. I didn't know before that such a option exists. Regards Stefan
