Hello,
I want to restrict all CLIENTS in 192.168.0.0/16 to send only to local
domains. That is 192.168.0.0/16 only can send between 192.168.0.0/16. I
have other public IP's that should be able to send any where. I am
subsituting domain.com for the real domain.
I am using.
smtpd_restriction_classes = local_only
local_only =
reject_unlisted_recipient
permit_auth_destination
smtpd_recipient_restrictions =
check_client_access cidr:/etc/postfix/clients_local_only
permit_sasl_authenticated,
permit_mynetworks,
reject_unauth_destination
So I have in /etc/postfix/clients_local_only.
--------------------------client_local_only-------------------------------
192.168.0.0/16 local_only
--------------------------client_local_only-------------------------------
I have in /etc/postfix/access all 64770 IP's with local_only:
----------------------------access----------------------------------------
domain.com OK
public_ip OK
...
192.168.0.1 local_only
...
192.168.255.254
----------------------------access----------------------------------------
I have now the above and below is my main.cf, but they can send outside of
192.168.x.x
