Thanks very much. I had tried adding "-o content_filter=smtp-amavis:

it when it didn't work.
Are you sure about the 10024? That is the standard Amavis port. If you
use the same port for externally inbound emails, they will be falsely
declared as originating.
Ok, I have more studying to do. I see there is a Configuring Multiple
Paths section which I guess I'll have to read.
For the Postfix bit, I already have:

Do I just duplicate the two sections starting 127.0.0.1, changing the
ports but leave the first smtp-amavis section?
