Believe it or not we're going to an external content filter and that's
why the change. I guess the next step would be asking if it's possible
to only allow connexions from allowed IPs to receive e-mail.


There are several examples of limiting connections to an external service in the archives. Something simple:
# main.cf
smtpd_recipient_restrictions =
  permit_mynetworks
  # uncomment next line if you use SASL
  # permit_sasl_authenticated
  reject_unauth_destination
  check_client_access cidr:/etc/postfix/allowed_client.cidr
  reject


# allowed_clients.cidr

10.2.3.0/28  OK
