A forwarder forwarding to another mail domain (i.e. not internal rewriting
of a mailbox, but really forwarding to another account) is a gateway.
RFC1123 does not agree with this. See my argument in
http://archives.listbox.com/spf-discuss(_at_)v2(_dot_)listbox(_dot_)com/200509/0302.html
Gateways change addresses. Gateways need to modify the mail from.
Yes, though forwarders are _not_ gateways, and forwarders do not change the
mail from (at least according to RFC1123/2821)
