Does Amazon EC2 support reverse DNS lookups for email sent from my instance?

If you modified the DNS for your domain (mydomain.com) to include a CNAME to the external DNS name of an instance, and send an email to someone from your instance [user@mydomain.com] a reverse DNS lookup will result in the external EC2 DNS name, not mydomain.com.
