If you're sure about this you'd say 5xx. Probably not to a
stupid MUA of your own users. Or if you support some kind
of AlterNic with a TLD .computer, but then you'd read any
"duties of a gateway" instructions very carefully. ;-)
Has the self-proclaimed host "oem.computer" a SPF record ?
Probably not, so that test should result in NONE. If you
never test it insisting on error 5xx it's fine, but that's
no SPF-"feature". It's also no SPF-"problem", it's simply
a non-issue for SPF.
