Ah!  If you want to stop spam that is a different problem.  What you
describe is exactly how it is suppose to work.  If you blocked delivery
to your local users then email would not be of any use to them.

But if you want to block spam then you need to install something like
spamassassin on your box.  I believe FC2 ships with version 2.63 which
is the latest.  You will need to spend time deciding how you want to
configure spamassassin for your server and if you want to handle it site
wide or let the users handle it at their level.  There are several ways
to configure it depending on how you decide to do this.

Check out the spamassassin web site and their documentation.  There is a
good day or so of reading and planning you will need to do to set this
up.
