Essentially, though I use postfix and that calls procmail directly.  
procmail calls spamassassin which returns the message with its analysis 
inserted into the headers.  procmail finishes the delivery process.

Idunno.  Try milter?  AFAICT, postfix can't.  Some of the other MTAs 
might, like exim.

I wouldn't mind the delay (only about 30 seconds), but it just consumes 
too much RAM.  Each spamassassin process uses about 16 MB on a 68k 
machine.
