Hi Gary,
Is there a way to make restrictions using CIDR notation?
Yes - just replace hash with cidr, like this: smtpd_client_restrictions = permit_mynetworks check_client_access cidr:/etc/postfix/ok_client reject More details: http://www.postfix.org/cidr_table.5.html Best regards, Matthias Am 19.02.2021 21:01, schrieb Gary Aitken:
I had the impression a map could contain client addresses in CIDR notation, but apparently not. Is there a way to make restrictions using CIDR notation? Here's what I was trying to do: smtpd_client_restrictions = permit_mynetworks check_client_access hash:/etc/postfix/ok_client reject /etc/postfix/ok_client: 209.85.128.0/17 OK $ ls -lt ok_client* -rw-r--r-- 1 root root 12288 Feb 19 16:35 ok_client.db -rw-r--r-- 1 root root 700 Feb 19 16:35 ok_client mail.log: 23551 >>> START Client host RESTRICTIONS <<< 23552 generic_checks: name=permit_mynetworks 23571 check_addr_access: 209.85.217.52 23572 maps_find: hash:/etc/postfix/ok_client: 209.85.217.52: not found 23573 maps_find: hash:/etc/postfix/ok_client: 209.85.217: not found 23574 maps_find: hash:/etc/postfix/ok_client: 209.85: not found 23575 maps_find: hash:/etc/postfix/ok_client: 209: not found $ postmap -q 209.85.217.52 hash:ok_client $ postmap -q 209.85 hash:ok_client $ postmap -q 209.85.128.0 hash:ok_client $ postmap -q 209.85.128.0/17 hash:ok_client OK Gary
