The spamming problem is not something that you can fix by replacing SMTP with something new. If you would configure your SMTPD to only accept strict standard SMTP stuff then you will see that this alone would remove much of the spam you get (just take for example the HELO/EHLO part. If you would strictly enforce what is described in RFC then a lot of spammers (and legitime) senders would be blocked. Not that I find this okay but just to illustrate that the protocol SMTP is not the problem). And today it is not big deal to cut down spam to less then 1% of the inbound. I really don't understand why people keep telling that spam is a problem? It is only a problem if you have not properly configured your SMTPD. Today it is so easy to cut down spam and most solutions don't require huge machinery at all.
