How would each forwarder know that the SPF record had already been
checked by the previous forwarder? Most forwarders, be it
If they *don't* know, then they should do SRS - so that the next MTA
checks their own domain, not a possible Dos victims.
So yes, checking SPF _for_a_given_domain_ more than once is braindead.
Braindead globally, but sensible individually. The trick then is to
convince forwarders to suboptimize locally to get a better global solution.
This is not a technical issue.
