I do what you describe and configure the MX records with the real
hostname. However I do have a mail.domain.com.au CNAME (actually at the
moment it's an A record for backwards compatibility) to allow customers to
point their "SMTP Server" configuration at something I can move around.
The parent domain has MX records listing the actual hosts.

Cheers.
