I have some statistics for SPF:
spam=> select count(*) from incidents where status = 'spam' and incident_report
like '%SPF query returned ''pass%';
count
--------
661769
spam=> select count(*) from incidents where status = 'spam';
count
---------
1003495
Looks like about 66% of our spam samples had SPF "pass". So
yes... spammers are setting up SPF records and/or using hacked
accounts. SPF is so easy ("v=spf1 +all") that it would be foolish
for spammers not to use it.
