regex not matching when using procmail and spamassassin

[Adriana Gonzalez]

Hi,

I am having the weirdest problem with my procmail setup.  When I add the 
spamassassin rule, every other rule fails to match.  Here is a 
section of my procmailrc:

-------------- begin snippet ---------------------

:0 fw
| /usr/bin/spamassassin

:0:
* ^Subject:.*SPAM
$HOME/mail/spam

:0:
*
$HOME/mail/incoming

--------------- end snippet ---------------------

If I send myself an email with subject SPAM, I get the following in my 
procmail log.  This behavior is the same for every other rule, that is, no 
rule that should match actually does when the spamassassin rule is 
present.

procmail: Assigning "FORMAIL=/usr/bin/formail"
procmail: Assigning "SENDMAIL=/usr/sbin/sendmail"
procmail: Assigning "DEFAULT=/home/adri/mail/incoming"
procmail: No match on "^Subject:.*SPAM"
procmail: Match on ""
procmail: Locking "/home/adri/mail/incoming.lock"
procmail: Assigning "LASTFOLDER=/home/adri/mail/incoming"
procmail: Opening "/home/adri/mail/incoming"
procmail: Acquiring kernel-lock
procmail: Unlocking "/home/adri/mail/incoming.lock"
procmail: Notified comsat: "adri@48054:/home/adri/mail/incoming"


Now, when I comment out the spamassasin rule and send myself the same 
message the rule starts matching again.....

procmail: Assigning "FORMAIL=/usr/bin/formail"
procmail: Assigning "SENDMAIL=/usr/sbin/sendmail"
procmail: Assigning "DEFAULT=/home/adri/mail/incoming"
procmail: Match on "^Subject:.*SPAM"
procmail: Locking "/home/adri/mail/spam.lock"
procmail: Assigning "LASTFOLDER=/home/adri/mail/spam"
procmail: Opening "/home/adri/mail/spam"
procmail: Acquiring kernel-lock
procmail: Unlocking "/home/adri/mail/spam.lock"
procmail: Notified comsat: "adri@1746:/home/adri/mail/spam"

Subject: SPAM
  Folder: /home/adri/mail/spam                                            1140


Any clues of what is going on and how to fix it?

Thanks,
