I should elaborate, perhaps I mis-phrased that. If you sign with DKIM, you 
don't need to know whether your recipient is using traditional forwarding. 
There's no work for you or the forwarder to do. It means that the recipient 
can determine the origin of a traditionally forwarded email.
With SPF, you can of course allow trusted third parties to forward email 
for you.
