NEVER set the null sender to a real mailbox. This creates mail

If however, a valid email address did not address the POP clients,

the interaction between the POP client and server, neither of which
is Postfix.
I've removed the null_sender from master.cf but can't see any change
in the Return-Path of the NDR's
NO DO NOT REMOVE from master.cf, rather set it EMPTY!

Adjusting the flags to your needs. Make sure that the transport
recipient for this transport limit is correctly set to 1.
This will correctly generate:
Return-Path: <>
when the original message is a bounce.
I don't get it, whatever I put in I just keep getting:
Return-Path: <MAILER-DAEMON>
