That is the standard setup for Postfix. But that does not mean your host
is an acting as an "open relay". Anyway, you can also tweak that
behaviour.
All I'm saying is that I don't need this, and I'd like to find a way to
shut it down whilst leaving the outbound mail delivery intact.
mynetworks_style = host
or
mynetworks = 127.0.0.0/8
I am using mynetworks_style already but it doesn't stop SMTP listening on port
25.
I guess this is just a relatively new situation coming with the advent of
vservers that just isn't possible.
I have set smtp_client_restrictions = reject so at least postfix responds to
external SMTP requests with an aggressive sounding "Client host rejected: access
denied" message.
