I have a simpler solution: separate those mail streams with separate
MTA instances. That avoids the complexity of adding exceptions to
main.cf, milters, ...
Different streams can have different filters/milters, which is more
flexible than a milter on/off switch.
The two MTA instances can run on the same host (bound to different
IP addresses) or on separate hosts.
