As has been pointed out, spammers are already going down this path with HTML 
encoded email.

These are useless since the spamming software (and often the spamming machine) 
is controlled by the spammer.  (Some of the most "interesting" spam I've 
received is for software to do spamming from a Windows PC without the need for 
an ISP mail server (complete with a list of open SMTP relays and other open 
proxies to use)).

Solutions must assume that the other side (the spam server) is totally under 
control of spammers, that the other software was completely written by and for 
spammers, that the other ISP supports spamming (it can be lucrative for the 
ISP), and that the ISP's connection to the backbone is supportive of spamming 
(spamming may provide needed hard cash for poor 3rd world nations).

This implies two things: spam control must be performed at the client SMTP agent 
and international organizations must be willing to censure countries that fail 
to police their assigned domains and addresses (i.e. cut them off).

We (the IETF) can work on the first.  Are we willing to push for the second? 
Without the second, we just have an escalating arms war (with, I fear, the 
advantage to the spammers).
