it's plenty possible that gmail is sending mail from servers not listed in their spf list. it's also very possible that their full spf list does specify all the outbound servers, but they exceeded the rfc-mandated limits on dns queries or the length of the result and thus a conforming receiver could drop mail. if you have access to the full headers and can use upas/spf (included in nupas), you can do the queries manually and see what happens. spf isn't hard to understand so you should be able to piece together the correct result by hand in ten minutes. - erik
