Following the firewall/smtp relay page
http://www.postfix.org/STANDARD_CONFIGURATION_README.html#firewall
Process
- internal servers *send* through *my-relay*
- *my-relay* forwards to *master-relay*
- valid email is passing through for all the clients as expected.
- *master-relay* kicks back any undeliverable emails to *my-relay*
I want the undeliverable email to be sent and received on *my-relay*
and not my work account.
- I work with end users to "fix" their undeliverable issue.
-- Bounce messages are *not* being received back from the *master-relay*
to *my-relay*.
