When scanning postfix bounce messages, I noticed this message:

" In: 501 bogus mail from"

Checking the local log (see below), the host mail.redrocket.com appears
to have not accepted a bounce message in response to a "relocated"
domain entry.

If my interpretation (regarding source of this being relocated) is
correct, then is there anything I should do to improve my error message
handling on local postfix to avoid the 501 from redrocket.com...?

Does the following log suggest that our current local postfix
configuration may need to be modified?

Here is the relevant information/log as seen from our local postfix
server (central.saas.nsw.edu.au):
