We're thinking that as well, or just stopping forwarding services at all.

The problem with forwarders using third party services' submission 
servers is that the user would need to give out their login details - 
which is a big issue. Maybe users should be able to create extra sets of 
authentication details for their submission servers, but ONLY for mail 
going to their own email addresses, for forwarding servers to use. These 
could still let the messages be blocked by a spam filter, but would let 
the receiving server know that the messages are coming from a forwarding 
server, so (a) the forwarding server's reputation should not be affected 
by spam from there, and (b) some checks like DKIM might have to be 
ignored/loosened.

I suppose that a scheme like this could potentially be extended to 
mailing lists - when you subscribe, you give authentication details as 
well as an email address.
