:-)I'd like to disable any mail from 'my.domain' from external networks and non authenticated users. For envelope addresses my solution works and is as follows:
At first bind valid addresses with their owners:
smtpd_sender_restrictions =
...
reject_sender_login_mismatch,
...
But this setting works for existing addresses only. That means that mail
from:
[email protected] still won't be rejected here. So the second restriction is: list1 = check_client_access hash:/etc/postfix/list_of_my_networks, reject smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_sender_access hash:/etc/postfix/file1 ... /etc/postfix/file1: my.domain list1 /etc/postfix/list_of_my_networks 1.2 OK 3.4 OKI'm not sure if it's the simplest solution but works fine... for the envelope. I'm wondering if I could apply the same during the DATA phase for the 'from:' field? Would be nice if you could do that similarly without involving any other filters / milters. Is it possible?
Best regards, Marek
