I am not clear what you are trying to do, but I doubt you'd need a
milter.  Postfix has robust rewriting capacities built in.

The generic(5) table is what you want [I think].   Postfix tables can
use flat files [w/regular expression], SQL, or LDAP.  There is also
socketmap and tcp if you really want to do something super crazy.
