The most likely cause is something wrong in whatever SpamAssassin sends
to dccifd.  Since dccifd seems to be saying 'A' or "accept" for both
the message overall and each indidividual recipient, I'd first check
the options line that starts the request that SpamAssassin sends to
dccifd.  My guess is that older versions of SpamAssassin sent "header."

What strace or ktrace says about what SpamAssassin is writing to dccifd
should make sense in light of the ASCII protocol described in the
Protocol section of the dccifd man page on your system or

It would also be good to check that dccifd is not whining about not
receiving mail headers or bodies in the system log.  Dccifd logs its
version number when it starts and some numbers every midnight.  If those
log entries cannot be found, something is not right in the -L args given
dccifd or in /etc/syslog.conf (or equivalent).
