I'm curious if you have already tried greylisting and found it to be
insufficient for the things you describe.  While it's true that a
dictionary attack can give you lots of greylisting records in short
order (depending on your implementation), that's still a heck of a lot
cheaper than runs of SA.  Greylisting was so effective here that it
has moved my constant worrying about SAs load to a secondary issue.
