We've got a customer whose emails (from other people but filtered by us) are frequently being rejected by Netstreams harsh SPF-check. I've asked Netstream to add our servers to their whitelist, but nothing has happened.
As a more generic alternative, you could implement SRS in order to handle forwarding in an ``SPF compliant'' way. This will fix the problem for all receivers which use SPF for scoring or rejection.
I am aware that this suggestion might well provoke yet another SPF/SRS flamewar :-)
