Re: Wot no SPF?
If you are simply forwarding mail, that has a tendency to break someone else's SPF rules
This is my point exactly. SPF falls down when someone has their email address set to forward elsewhere, because the original sender didn't "authorize" their email to be sent by another other server. You can't rely on every mail server out there that allows email forwarding to another server to have implemented SRS.
It also doesn't "stop SPAM" in and of itself. It simply makes it where someone can't impersonate your email address in the envelope sender. Spammers could just as easily create SPF records for their own throwaway domains authorizing the world (but luckily they rarely do).
