Per-message hooks would certainly be more complicated than with, for 
example, getmail where mail is only going in one direction.

For my current needs, I think isbg ( will do 
the job -- it keeps track of which emails it has seen before, so it can 
just be called via cron or as a post-sync hook from offlineimap, and it 
will move spam to a suitable folder that will then get re-synced by
