So to SUM things up.. buy the O'Reilly Sendmail "Flying Fox" book 3rd 
edition..(which is a bit different from the 2nd edition ) and read it..  
in this case CP 7.5.*   =)
 
FEATURE(`access_db', `hash -o -T<TMPF> /etc/mail/access') -- Access DB 
for  >= V8.12
FEATURE(`delay_checks', `hater')dnl   -- to reverse the order in which 
the access DB is checked -- check RCPT TO first then everything else.  
the second 'equate' hater/friend determines how check_rcpt will work -- 
`hater' seemed to be the better choice to me.
FEATURE(`blacklist_recipients') -- I think this must be defined to use 
the Accept and Reject per Recipient feature..

You would 'makemap hash some_text_file > access' to create your access 
DB formatted in the correct way (very similar to virtusertable stuff)

To:postmaster@   OK
To:user1@         OK
To:user2@         REJECT -- or ERROR:550 we don't want mail to this user

There's all kinds neat things you can do here.  I have been working on 
all this myself VERY recently ;) and will be testing it soon.. but this 
is the 'theory' I've gathered so far. 

Speaking for myself putting together the access db is going to be my BIG 
challenge.. and my Perl experience is 'lacking'.

Anyway hope I helped abit..
