You don't appear to have told postfix that it accepts mail for
ussupport.co.uk.

This makes postfix think that you're asking it to relay, and it's set
up to deny relaying, hence the bounce.

There are a half dozen ways to configure postfix to accept mail for
ussupport.co.uk depending on what you're doing.  The simplest may be
setting mydestination, but review the postfix docs so you know if you
want that vs a virtual host.
