Hi Greg,

I think, it's impossible with only one postfix instance

Assumed you have small setup like this: http://www.postfix.org/ADDRESS_REWRITING_README.html#overview
milter are not involved on rewriting messages and sending them to a remote destination

you need at least two postfix instances.

1. receive
   pass to an arc milter in validation mode
   rewriting / forwarding to a relay_host (2)

2. reveive _only_ from (1)
   pass to an arc/dkim milter in signing mode
   deliver to remote destinations
