Either the MTA is not authorized to send a message, or it is.

If a message is rejected due to "-all" or alike, this will never
be a false positive.  It is a configuration error or it is fraud.

If a message is rejected for other reasons, such as "?all", "~all"
or alike, it also is a configuration error and thus not a false
positive.  In this case, the config error is on the receiver's end
or on an intermediate MTA.

I get the feeling you think false positives are possible with SPF.
Please discuss.
