a) sieve is a line oriented parser that keeps its state.  You have a:

     for line in mail:
         sieve_add(line)

b) sieve is sent the entire mail for parsing


as I recall sieve goes something like:

  if message_subject == $known_subject
     save_to($known_subject_folder)

  basically, it's syntax knows about mail and defines actions to be performed. 
The sieve interpreter should take hooks so that when a 'save_to' operation
happens, it calls mailutils' save message to folder function.
