"A smart IM2000 recipient perhaps would not pull spam from the sender's server." Based on what criteria? You wouldn't have the message headers/content, so you couldn't filter based on that. All you can filter on is the IP address. But you can already do that with SMTP by just responding with a 5xx code as soon as the sending server connects anyway... Or you could actually fetch the message and then spam filter it. But then, you may as well use SMTP... What difference does it make which side initiates the TCP connection? If I was a spammer, IM2000 wouldn't concern me one little bit. |
