May 7, 2016 at 21:43 comment added Hagen von Eitzen SPF is not used to find out what server you used. SPF (if employed by the sender's domain) is a means to allow receiving MTAs do detect mail originating from unauthorized sources. Some major SPFs would allow gazillions of servers, simply because those big providers do use gazillions of outbound mail servers. SPF has nothing to do with submission. The closest to tracing back the origin (from within the mail) is the Received: header - which might be cut off or filled with deceptive fake info by any server before the first of an uninterrupted chain of servers you trust
