Sometimes when one of these gets through to my eyeballs I will pester the postmaster at the bouncing site to implement SPF checking (or make sure that their set-up still respects spf-classic syntax). Given some organizational tuits, statistics on origin of blowback bouncing SPF-invalid spam could be used as a flimsy clue stick. -- "Simplicity is one of the most misunderstood concepts in programming" -- Matz
