I use http://www.dnsexit.com/Direct.sv?cmd=mailRelay to get around port 
25 blockage at home and also avoid going into the spam blackhole.  It 
has an option for no authentication if coming from a defined IP 
address.  That gets around setting up any kind of smarthost authentication.

Just make sure your box is not an open relay.
