Did you look at the spammassassin configuration options?

   From the Mail::SpamAssassin::Conf manpage (SpamAssassin version 3.1.8)

   NETWORK TEST OPTIONS

   trusted_networks ip.add.re.ss[/mask] ...   (default: none)
       What networks or hosts are 'trusted' in your setup.  Trusted in
       this case means that relay hosts on these networks are considered
       to not be potentially operated by spammers, open relays, or open
       proxies.  A trusted host could conceivably relay spam, but will not
       originate it, and will not forge header data. DNS blacklist checks
       will never query for hosts on these networks.
