You did update your mail server definition of your hostname? If your mailserver program (postfix, sendmail, whatever) thinks something is going to a different hostname than what it expects, it will bounce it. Make sure your mailserver knows about your dyndns.org address and doesn't just think it's something like ....nc.rr.com.
