It doesn't matter if the mail is forwarded. If you're sending a mail for
a domain which has an SPF record, and the recipient server is known to
be broken (i.e. reject for SPF failure even though that's stupid), and
if this host is not listed in the SPF records for the sender's domain,
then rewrite.
That's essentially the logic in the 'rpr_outgoing_goto' router in
http://david.woodhou.se/eximconf/include/routers-ses -- except I didn't
bother with the last check.
As it happens though, my list of broken recipients is almost empty --
most times when they reject mail due to SPF failure, I contact them and
explain why they're rejecting valid mail, and they stop doing it.
