Yes, pretty nearly exactly.  But you don't need to use a regexp; you
can use a simple sender access map in any Postfix map format such as DB
hash/btree/SQL/whatever:

  ...
  check_sender_access exempt_senders,
  ...

exempt_senders:
  senderdomain.tld      FILTER 127.0.0.1:10025
  
  etc.

  I have had this working in production for well over a year now.
