What's your trusted_networks set to?

If you don't have one, my guess is that SA is mis-judging where your network
boundaries are. This is VERY common, particularly if your mailserver is behind a
static-NAT or otherwise has a reserved IP address.

By default, SA will guess at trusted_networks, and copy that to
internal_networks. Any host in internal_networks is immune to RBL checks.
