It is, regrettable not so simple.

Since there is a gazillion of possibilities to integrate spam scanning,
how exactly did you do it? Can you give the entire relevant part of your
configuration?

This will disable spam scanning for authenticated messages, not for
outgoign messages. Very different. For example, messages coming in from
a machine listed in dc_relay_nets would be scanned anyway.

What you want to do is non-trivial in the package since it needs
information about the entire site's configuration as soon as the site is
a non-trivial setup.
