Spamassassin, greylist, and sendmail

[Steven Stern <subscribed-lists sterndata com>]

I'm trying greylisting as a way of reducing spam.

By themselves, both milter-greylist and spamass-milter work OK.  When I
combine them, spamass-milter dies with the error "cmd read returned 0
expecting 5"

It seems that the problem is with the milter macros required by
milter-greylist. If they defines following the greylist milter are
uncommented, then I have the problem with spamass-milter.  I'musing
spamass-milter 0.2.0.

Suggestions?  (Yes, I know, use MimeDefang or Amavis.  But right now, I want
to see if I can solve this problem.)
