upgrade to spamassassin-2.55

Hi,
i have fetchmail, sendmail, procmail and spamassassin 2.44 running and
everything works like a charm.

as the description of the rpm-package of spamassassin says, i just added:

PATH=/bin:/usr/bin:/usr/bin
INCLUDERC=/etc/mail/spamassassin/spamassassin-default.rc

to my /etc/procmailrc and changed my spamassassin-default.rc in the
/etc/mail/spamassassin/ to:

# send mail through spamassassin
:0fw
| /usr/bin/spamassassin

:O w
* ^X-Spam-Status: Yes
/var/log/Spammail.txt

So, as i said, everything works fine here, my spams are filtered and written
to /var/log/Spammail.txt.

Now i tried to freshen up to version 2.55 (rpm -Fvh spamassassin.rpm),
because i would like to use sa-learn.

the description of the new rpm-package from fedora.us (rh 9.0.93) is the
same, so i did not change the /etc/procmailrc and the
spamassassin-default.rc.

i tried the following to test the filter:
cat /usr/share/doc/spamassassin-2.44/sample-spam.txt | mail user


But NOTHING is filtered anymore? Why?
