It all depends on what you mean with "easy to set up". You will
certainly have to use a policy daemon with postfix. 

in main.cf
smtpd_recipient_restrictions = check_policy_service unix:private/spf

in master.cf
spf       unix -    n    n    -    10   spawn user=nobody
argv=/usr/local/bin/spf.pl

with spf.pl being the policy daemon from
http://www.openspf.org/postfix-policyd.txt
