Technically not, your IP resolves to a Rogers hostname, that is controlled by 
Rogers and nothing you do with dyndns.org will change that.

I expect you'll need parameters something like this:

myhostname = mail.subdomain.dyndns.org
myorigin = subdomain.dyndns.org   
append_dot_mydomain = yes  # Skip this if you like
mydestination = subdomain.dyndns.org
relayhost =         # Needn't be specified, here to show that it is not set

As long as your machine has functional dns things should just work.  Postfix 
will lookup mx records for other domains and relay mail directly to the 
appropriate host.

Relaying directly from a dynamic ip pool you will run into sites that 
blacklist your mail.  For that reason, and for technical satisfaction, you 
may wish to pursue authenticated relaying through Rogers servers ... I 
haven't set that up before so I can't offer any pointers.
