module can not be used at a relay

[toepi]

to use this module on a gateway/relay it must also managed InternalHosts.

Default content (worked also without wildcard support) can be

127.0.0.1
localhost
$::network_eth0/$::netmask_eth0

Not sure if it better to use refile:/etc/opendkim_trustedHosts to allow wildcards.

To enable this kind of function a flag should be included (like relaymode) which has false as default.

I think 41230b3 enables managing InternalHosts. I'm using it on a relay, and it seems to work OK.
