On my small system I have the same experience. Nobody sends mail that you want from nonexistent domains. >I'm not sure I'd make the same decision based on the lack of an SPF record, I certainly wouldn't. I get plenty of mail from addresses with no SPF record. I think some of it is even DKIM signed.
