That's a common misconception about SPF (mostly promulgated it seems by
the opponents of SPF). SPF is all about preventing forgery and only
incidently may be somewhat useful to stop outright spam.
What is far more likely is that spammer will find the lazy
administrators who set up an SPF record with '-all' and use those
domains exclusively to forge their return addresses. Of course, that in
itself will lead to sites using SPF to discount *any* record containing
'-all' so spammers will not be able to use this for very long.
