	you must explicitly allow the virtual websites addresses to 
	use your machine as a relay.

	your anti-relay rules probably include allow mmail to/from $=w
	(all the names of your mahcine).  define a classs, say "R", 
	and add all the virtual website, forwards and aliases to it.
	the copy the "$=w" rule and chnage the copy from "$=w" to
	"$=R"
