I have a complex postfix setup with dovecot authentication, amavis and spamassassin.
The inet_interfaces are set to my IPv4 address, IPv6 address and IPv4 and IPv6 loopback. But I want that the submission service only listen on the public IP addresses and not on localhost addresses. How can it set this?
-o inet_interfaces= public ipv4, public ipv6 in master.cf does not work.
