If you forward such mail you should know something about the site that you are 
forwarding it to.  If the recipient site is doing SPF checks then your 
forwarding system needs to do the appropriate SPF mangling or the recipient 
site needs to add the forwarder as an exception to the SPF policy.  In either 
case it shouldn't be difficult to do.

The only situation in which SPF is a problem is when someone wants to setup 
forwarding but has no control over anti-spam measures on the destination host 
or the forwarding mechanism.  Is it common that users will have such a lack 
of control when using systems that implement SPF?
