e.g. I've talked to people who say that 90% of the SPF records they
see are from spammers.
That is certainly not what I am seeing here. Granted it is only a
small sample (as I do not keep spam for long) and as I use SPF on the
MTA I do not see SPF Fail (as they are refused). In my spam folder at
the moment, I have
SPF Pass 0
SPF None 203
SPF Neutral 5
SPF Soft-Fail 6
SPF Unknown 4
