most smtp's will never send to numeric ip addresses as a precaution. if you really need to do this then you need to setup an smtp that explicitly allows this and will relay mail for you - you probably don't want to go there.

If you can get some dyndns service up you might be able to use the @host.dyndnsservice.whatever hostname instead, providing MX records are setup OK.
