Rejecting on the basis of SPF -ALL without waiting for DATA is cheap in resources, obeys the published policy of the sending domain owner, and affords the Recipient the benefit of off-loading the blame for the rejection onto the Sender. Also, rejecting on the basis of SPF -ALL does not inconvenience at all mailing list traffic, as mailing list traffic usually takes ownership of the Return Path (envelope MAIL FROM), so if the mailing list host has an SPF record, its traffic will pass an SPF check without waiting for DATA.
