Errr, yes, that's what I meant, and that's what I use in conjunction 
with virtual domains on my servers. But you're right of course, if you 
don't care about one local user sending mails purporting to be from 
another local user then a single lookup for a per-domain sender access 
map is a more efficient way of dealing with spoofing.
