I must be doing something silly, but I can't see my mistake. $ postconf postscreen_dnsbl_sites postscreen_dnsbl_sites = zen.spamhaus.org=127.0.0.[2,3,4..8,10..11]
postfix/postscreen[26161]: fatal: bad DNSBL filter syntax: need "," or "]" at "127.0.0.[2><" Or to simplify the matter: $ postconf postscreen_dnsbl_sites postscreen_dnsbl_sites = zen.spamhaus.org=127.0.0.[3,4] postfix/postscreen[25207]: fatal: bad DNSBL filter syntax: need "," or "]" at "127.0.0.[3><" Without a filter or with just a plain dotted-quad it works normally. This is postfix-2.8.0-RC2, FreeBSD, installed from ports mail/postfix-current after adjusting the version of a filename and a checksum. Mark
