Submission + - gmail's policies are abusive to small ISPs 1
galexand writes: My gmail-using friends were not getting my email, so I investigated. Similar reports abound, with suggested resolutions ranging from fixing your DNS to adding SPF, but many cases remained unresolved. So I putzed with my DNS, postfix, and SPF settings for a couple days and now my headers look perfect to me but gmail is still labeling my email as spam. This appears to be an intentional policy on google's part — they just assume that most small servers are run by spammers and accept that they'll knock off the occasional small business. The trouble is that gmail is so large that they can unilaterally redefine email, but they aren't publishing their specs so we can't conform. What can we do about this kind of abuse from big providers?
