That rather depends on a) exactly what your problem is, b) what MTA you
Taking these points in turn...
Is your problem 1) affecting some mails leaving your networks, or...
2) all mails entering your network
if 1) then odds are its an external site with misconfigured DNS (some
spammers use MX records of 127.0.0.1 to avoid getting bounces) - in this
case its outside your control.
if 2) Set your Mailscanner server as secondary MX instead of primary
and ensure your primary MX is firewalled not to accept connections from
the outside world. Or if you are using sendmail set up mailertable
entries for your local domains to bypass the DNS lookup. (I guess there
are similar techniques on other MTA's)
