You can't. Maybe Kevin Snook already has a utility to help you.

How do I set up a "catch all" postmaster account that accepts all mail
except those with specific mailboxes WITHOUT having to build a list of
bogus e-mail address that will be accepted.

I've not read all of this email so I may be repeating what has already
been said, so apologies if that is the case, but there are 2 things
you
can do.
You can set up a 'catch-all' postmaster account that would receive
these
emails, or you can add these email addresses as secondary proxy email
addresses to other mailboxes, i.e. the administrators.

Yes, I realized that after I sent it. The real problem is that I am
up to over 60 non-existent e-mail addresses. I don't want to have to
track each bounce and manually add it to the distribution list. More
preferably, I would like to block (issue a reject) the message before
it even gets into the input queue. This might discourage the
spammers.

Huh? If you assign an smtp address to a DL with no members, the
message
just disappears & no NDR is sent.
or am I just confused 'cause I've been sick?

From the comments here, it seems that you can't set up exchange 5.5 to
do
what I was originally looking to do: Either reject outright a message
without a mailbox, or simply not send an NDR for a message without a
mailbox.
This seems to be what I am hearing? Is this correct?
The idea of dropping the messages in a black hole won't do what I
wish: an
NDR will be sent to the sender.

Always a good thing to think, especially if it reduces your
workload/aggravation quotient.

That's a good idea (I'll create it but then just won't tell anyone
else -
theoretically still busy....)
Now that's 2 people on this list that have made me think today. Is
this a
good thing? :-)
