Yeah, but in that case sendmail aborts the message and spamass-milter
never gets to process it completely.  I have been creating 0-byte
messages with

print 'ehlo mymachine\nmail from:<address@hidden>\nrcpt 
to:<address@hidden>\ndata\n.\nquit\n' |
 nc dan smtp

(replace address@hidden with your own email address, and dan with your milter
server).  That submits a 0-byte message.  Make sure that the netcat
command connects to the machine actually doing the miltering, since if
it has to hop to another server, it'll most likely add a Received:
header, which makes the message more than 0 bytes long (the size
includes headers).
