I don't see how push or pull fundamentally changes the spam equation in any case. The problem wrt spam is the any-any nature of who you receive communication from, not who initiates the connection. I can create a walled garden trivially with smtp just be rejecting connections from people not on my whitelist. Likewise, anything that is promiscuous with who it receives from better be prepared for mail-transmitted diseases (MTD's). That's just the nature of opening up. So SMTP itself isn't the problem, or more specifically fretting about SMTP is nipping around the edges of 20 with the 80-20 rule.
