Yes, because /etc/mail/local-host-names is the wrong place for that.

When you tick the box for "disable all email" for a site, then the following 
lines gets added to /etc/mail/access:

### Start Block Email for Virtual Site: site4.smd.net ###
www.site-in-question.com           ERROR:5.1.1:550 User unknown
### END Block Email for Virtual Site: site4.smd.net ###

That'll then make sure that all email to that site is rejected with a "User 
unknown" message.
