You can also hijack milter-greylist for doing it, with the new
URL check feature: you'd need this config in milter-greylist on backup MX:

urlcheck "usrok" "http://mx1.example.net/usrok.cgi?rcpt=%r" 10

acl whitelist rcpt /@example\.net$/ urlcheck "usrok"
acl blacklist rcpt /@example\.net$/ msg "invalid user"

Then in http://mx1.example.net/usrok.cgi, implement the following logic:

if (valid($rcpt))
	printf("milterGreylistStatus: Ok\n");
else
	printf("\n");
	
The code for that is in CVS and has not made it into a snapshot release. 
syntax and interface is therefore subject to change.
