Thanks Bill & Jeremy for your responses - that all makes sense and is clear.

My specific issue is that I'm experimenting with a small setup on AWS
(Lightsail), and all outgoing email has to go via Amazon SES; it is SES
which is rejecting the bounce messages.

I'm wondering therefore if anyone has experience in this particular
situation which they might share (besides the obvious advice of "Don't
put a mail server on Lightsail" :-) ). I can live with sending bounce
emails to a specific local address, rather than back to the original
sender of the email.... will explore that too.

Thanks,

Ray.
