Today I noticed that, occasionally, I see a syslog message stating "blocked using zen.spamhaus..." but no matching "DNSBL rank ..." message.
A couple of examples from the past two days: postfix/postscreen 84893 - - CONNECT from [43.157.61.211]:30092 to [192.168.11.2]:25 postfix/dnsblog 84894 - - addr 43.157.61.211 listed by domain zen.spamhaus.org as 127.0.0.11 postfix/postscreen 84893 - - HANGUP after 3.2 from [43.157.61.211]:30092 in tests before SMTP handshake postfix/postscreen 84893 - - DISCONNECT [43.157.61.211]:30092 postfix/postscreen 1274 - - CONNECT from [45.83.66.127]:42402 to [192.168.11.2]:25 postfix/dnsblog 1276 - - addr 45.83.66.127 listed by domain zen.spamhaus.org as 127.0.0.11 postfix/postscreen 1274 - - HANGUP after 5.3 from [45.83.66.127]:42402 in tests before SMTP handshake postfix/postscreen 1274 - - DISCONNECT [45.83.66.127]:42402 postfix/postscreen 1292 - - CONNECT from [64.62.197.225]:56707 to [192.168.11.2]:25 postfix/dnsblog 1294 - - addr 64.62.197.225 listed by domain zen.spamhaus.org as 127.0.0.4 postfix/postscreen 1292 - - HANGUP after 4.5 from [64.62.197.225]:56707 in tests before SMTP handshake postfix/postscreen 1292 - - DISCONNECT [64.62.197.225]:56707 My postscreen_dnsbl_* settings are: postscreen_dnsbl_action = enforce postscreen_dnsbl_allowlist_threshold = -1 postscreen_dnsbl_sites = zen.spamhaus.org*2, list.dnswl.org*-6 postscreen_dnsbl_threshold = 2 Some other syslog records do have the DNSBL rank. For example: postfix/postscreen 86907 - - CONNECT from [185.242.226.22]:49012 to [192.168.11.2]:25 postfix/dnsblog 86910 - - addr 185.242.226.22 listed by domain zen.spamhaus.org as 127.0.0.3 postfix/postscreen 86907 - - DNSBL rank 2 for [185.242.226.22]:49012 postfix/postscreen 86907 - - HANGUP after 0.8 from [185.242.226.22]:49012 in tests after SMTP handshake postfix/postscreen 86907 - - DISCONNECT [185.242.226.22]:49012 My syslogd (and system as a whole) is far from busy.
