> a forged email pass anyway A forged email using a subdomain for which no SPF record exists will pass the test checks against SPF fails, something which some spam-filters include, as it's a cheap way to get rid of a chunk of spam. Such a forged email will NOT "pass" SPF. It is in theory possible that there is a incorrectly configured spam-filter out there that gives you an easy ride if you use an SPF-less subdomain in the SMTP envelope. I doubt this is the case, but if it does exist, please do tell its developers to fix their filter. > I think is a misunderstanding of a huge part > of the operators Is it? Have you evidence, even if it is only anecdotal, that such a misunderstanding exists? If so, as Dave said, we should consider writing better documentation.
