It seems to me that if we make all MTA's register somehow (both SMTP and POST), this would eliminate the hijacked machine as spambot phenomenon. We already have MX records for SMTP, but a lot of providers use different machines to receive (via SMTP) and send mail (POST). So, maybe a new DNS record is introduced for POST. Your machine(s) could do both or not. When your server goes to accept a message, it looks to see if the IP of the sending machine is listed in this new DNS record. If not, return a 5XX error.
