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

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.
