This seems to be a problem in your postfix configuration... you did
configure it, right? At the very least, you'll want to:
edit /etc/postfix/aliases # set alias of root to your username to get
                          # admin mail
postalias /etc/postfix/aliases # hash this table
edit /etc/postfix/main.cf # edit a few things here:
	myhostname # shouldn't need to change this from the default
                   # (unspecified, it uses the value set in /etc/rc.conf
	mydomain   # again, shouldn't need to change this unless you
                   # didn't set it in /etc/rc.conf. If your box isn't a
                   # mail host online, then just ignor ethis entirely..
	myorigin   # you probably want to leave this as the default
                   # $myhostname
	inetinterfaces = localhost # this makes your mail daemon not
                                   # listen on network interfaces for 
                                   # new mail
	mydestination = $myhostname, localhost.$mydomain, localhost
		# if you know why you need it, you can append other
		# things here. Otherwise, stick with those three.
	mynetworks_style = host
		# don't trust remote users, don't relay their mail. This
		# is probably redundant in light of inetinterfaces being
		# set to only bind to localhost, but paranoia is good.

Now, fire up postfix: /etc/rc.d/postfix start

Use sendmail to make sure mail sent to root ends up in your mail spool:

And check that it ends up in the local mailspool. If you use a gui
client to read email, any decent one should be able to add a local
mailspool. It'll be called "unix mail" or something like that. The spool
is at /var/mail/$user

Now you have mail delivery set up on your local machine.

Now, as for ddclient... it is, in my opinion, crap. Use updatedd. I've
attached a package build. Edit the configuration of your service in
/usr/etc/updatedd-wrapper.conf, and then put updatedd-wrapper in a cron
job. Do, as root:
> # crontab -e
and then insert this line:
*/10 * * * * /usr/bin/updatedd-wrapper
which runs the updatedd-wrapper script every ten minutes.
