Don't You use some other anti-spam tool? I don't, as I haven't found any 
good and fast and nonperl based software. Dspam is close, but I haven't 
yet figured out how to set it up with global quarantine.

Now, the sendmail with rbl -s + milter-greylist works pretty fine for 
me, however I'm also interested some more protection, about Your idea, 
maybe some procmail filter which parses the url and adds this to 
milter-greylist -s blacklist (we do need something like this) also will 
work. But this isn't actually the solution, as You told, all messages 
are different, so You catch the ip addresses which never return anyway.
