BTW the DNS A-record lookup done on spf.messagingengine.com isn't relevant - it should have been a TXT look-up.
It may appear to work at FM if they've set up the IP addresses for spf.messagingengine.com to match its SPF record, but it's certainly not definitive, so there's no guarantee that it's consistent with the correct look-up.
include:spf.messagingengine.com means lookup the SPF for spf.messagingengine.com and look for a pass on that. You can't get a fail from an include so the term "include" is really a misnomer.
