Here is what I use as a starting point, for those domains which publish SPF.
(See, it's not entirely useless.)
# host -ttxt gmail.com
gmail.com text "v=spf1 redirect=_spf.google.com"
# host -ttxt _spf.google.com
_spf.google.com text "v=spf1 ip4:220.127.116.11/23 ip4:18.104.22.168/19
ip4:22.214.171.124/20 ip4:126.96.36.199/18 ?all"
We also have a "trusted domains" list which bypasses greylisting when a
domain we call trusted publishes SPF and the SPF result is a "pass" of some
sort. (Our home-grown greylisting daemon makes that decision, so I can't
post useful stuff about it.)
