site wide spamassassin doesn't do bayes...

[Peter Teunissen <lists@onemanifest.net>]

Hi all,


I'm having trouble getting spamassassin to do site wide bayes. I've  
got it trained with sufficient ham and spam and when I try it with  
spamassassin -D < testmessage as root, it works fine. When I run it  
as user filter it fails. It tries  to create userprefs and it can't  
access the bayes db and whitelist:

==== output ====

I'm running spamc as user filter invoked by postfix on Debian Sarge.
In /etc/postfix/master.cf:

spamassassin
          unix  -       n       n       -       -       pipe
  user=filter argv=/usr/bin/spamc -f -e /usr/sbin/sendmail -oi -f $ 
{sender} ${recipient}


In /usr/share/doc/spamassassin/README.Debian it reads:

Configuring spamd
-----------------

If you intend to use Bayes sitewide, you will need to create a
world-writable and world-readable directory. /var/spool/spamassassin
is recommended as an FHS-compliant path. You will then need to add the
following lines to /etc/spamassassin/local.cf:
        bayes_path        /var/spool/spamassassin/bayes
        bayes_file_mode   0666

If you intend to run spamd as a non-root user, you will need to ensure
the pidfile to which spamd writes its PID is writable by that
user. The best way to do this is to create a directory
/var/run/spamassassin with appropriate permissions which will hold
this file.


So I added the settings to local.cf and added the world readable &  
writable directory:

mrblue:/# ls -lh /var/spool/ | grep spam
drw-rw-rw-   2 root     root     4.0K 2006-09-26 20:07 spamassassin

mrblue:/# ls -lh /var/spool/spamassassin/
total 4.6M
-rw-rw-rw-  1 root root  12K 2006-09-26 20:07 auto-whitelist
-rw-rw-rw-  1 root root 5.1K 2006-09-26 20:07 bayes_journal
-rw-rw-rw-  1 root root 632K 2006-09-26 20:07 bayes_seen
-rw-rw-rw-  1 root root 5.2M 2006-09-26 20:07 bayes_toks


Am I missing something? And should I look into this PID file issue   
mentioned in the readme? filter does seem to run.


TIA
