No, the rdns check is done as such:
ip address -> fqdn lookup
lookup the fqdn you got back and make sure it maps to that IP address.
After doing that, you log the connection as having come from
colo231.foo-provider.com and ignore the fact that mail.foo.com also happens
to point to the same IP address.
