So if I understand this correctly, domains which receive their email

not the originating domain's outbound server?

You don't do SPF checks when receiving mail by ETRN.

More generally, you should always know your "front runners" -- regardless 
whether they are ETRN services or classic forwarding services -- and 
exempt ("white-list") them from SPF checking.  Either you trust your 
forwarders not to forward you any crap (then don't do SPF checks), or you 
don't (then why would you use their services?).
