If a domain has an SPF record, then it should be taken as authoritative.
So if the SPF test fails, the mail is spam.
Many domains, such as hotmail.com, have SPF records that allow for
If a domain *does not have* an SPF record (as in Hans' case) then the
lack of such a record cannot be used to declare mail from that domain
spam. Yahoo.com does not have SPF records.
SPF records are voluntary, not mandatory. I would never run a domain
without an SPF record, because it can be very effective at preventing
spoofing. But I would never reject mail from a domain because it lacked
an SPF record.
