pen and spamass-milter

Sorry for cross posting, I'm not clear if this is a spamass-milter or
pen issue. Or both.

I've been attempting to use pen to load balance spamassassin. I talk to
spamassaassin
via spamass-milter.

The theory is:

sendmail->spamass-milter->spamc->pen (listening on port 783)->spamd on
two machines

But it doesn't work. Spamass-milter fills mail.log with "Could not
extract score from <>"
and my headers are no longer updated with spamassassin scores. So
something is
wrong but I don't know if it's pen or spamass-milter. All works fine
without pen.

Pen is started thus: "pen 783 localhost:10783 packard".

Spamass-milter is started with OPTIONS="-u spamass-milter -i 127.0.0.1
-i 192.168.1.0/8 -i 217.157.23.243 -r 15 -I"
in /etc/default/spamass-milter.

On the localhost spamassassin is started with OPTIONS="--create-prefs
--max-children 6 --helper-home-dir -p 10783"

On the "packard" machine spamassassin is started with
OPTIONS="--create-prefs --max-children 5 --helper-home-dir"

This is Debian5.0 Linux on an x86.
