Except on Debian systems where it might not work, because the Debian
"postfix-files" file (in $daemon_directory for recent enough
releases) often has more files list than are actually deployed by

Some time ago, I'd cribbed the following postscreen dnsbl weights from an

postscreen_dnsbl_threshold = 5
