Yes, sorry.  I'm blind!

I'm not sure how...what is the use you see?  How on earth do you really intend 
to stop these people from sending mail?  You have to force them to use your 
SMTP server, and block nearly all of their access to the internet to ensure 
they can't send E-mail, and you better hope they don't go home and send mail 
from their work account from there.

If it's an attempt to increase productivity, it won't work.  At every 
corporation I've been at that has network restrictions, the majority of 
people spend more time trying to get their work done around them than 
anything else.  The last one I worked at had only ports 80 and 443 open, 
which made everything really difficult to do.  You'd hear people talking on 
the phone complaining about "the d*** firewall" and related problems all day 
long.  Those of us who were more technical set up SSH servers on port 80 and 
tunneled everything anyways.  You can do that even on a Windows machine 
without local administrative rights, which I later just took home and 
formatted out of frustration (after that I worked much more 
efficiently ;-) ).

There are commercial mail servers providing lots of things that are bad ideas.  
And most mail servers have at least one oddball feature that you won't find 
in any other package.

One of my favorite quotes is "It is better not to do something than to do it 
poorly." (from Andreas Hanssen, author of BincIMAP).  This is one of those 
things that cannot be done well because of how the SMTP mail infrastructure 
works.  If it only works 90% of the time, that's what I call "broken", or a 
flawed idea.

Well it's certainly possible to create something...likely you won't want to 
accept these at the SMTP level at all, so the best solution I can think of 
would be to write a custom SMTP server like rblmstpd that instead of checking 
RBLs, checked a local database for an allowed recipient domains list for the 
account trying to send, or simply a boolean external value as you propose.
