Basically the netspace.net.au domain lists asav.iinet.net.au as the mail exchanged for the domain. https://intodns.com/netspace.net.au

Looking at the setting advertised by iinet https://help.iinet.net.au/email-settings I would suggest you try using the iinet SMTP server name instead of netspace.net.au
