I can add it to recipient restrictions, but I don't want to affect
general
incoming mail.
smtpd_recipient_restrictions =
...
check_policy_service inet:127.0.0.1:10031,
...
Is there a safe way to add it to the submission service directly?
Add an override in the master.cf file for
smtpd_recipient_restrictions
to the 'submission' entry.
What would that look like?
submission inet n - n - -
smtpd
-o smtpd_tls_security_level=encrypt
-o smtpd_sasl_auth_enable=yes
-o smtpd_recipient_restrictions={check_policy_service
inet:127.0.0.1:10031,permit_sasl_authenticated,reject}
-o smtpd_relay_restrictions=permit_sasl_authenticated,reject
-o milter_macro_daemon_name=ORIGINATING
-o receive_override_options=$submission_overrides
-o syslog_name=postfix/submission
-o sender_dependent_default_transport_maps=
-o sender_canonical_maps=
-o sender_canonical_classes=
-o recipient_canonical_maps=
-o recipient_canonical_classes=
-o smtpd_milters=
-o non_smtpd_milters=
-o milter_default_action=tempfail
Looks reasonable. I assume you have good reason for all the other
overrides.
