Thank you, Steve, your last question prompted me to rethink what was
going on. I am calling spamc via dman's SpamAssassin/Exim 3 method 
(which must run as user mail to set $received_protocol) but calling 
sa-learn as my user. I had another look around, and it looked like the
auto-learning was happening in /var/mail/.spamassassin, while I'd 
only been looking in my ~/.spamassassin dir

I re-read `man spamd` (among many others), and decided I would just 
employ a system-wide bayes_ db -- nobody else really uses the box right 
now anyway -- so I added this to /etc/spamassassin/local.cf:

 bayes_path /var/mail/.spamassassin/bayes
 bayes_file_mode 0664

which I expected to have permission problems with. The original
permissions were:

 # ls -lA /var/mail/
 drwx--S---    2 mail     mail         4096 Sep  1 00:11 .spamassassin
 # ls -lA /var/mail/.spamassassin/
 -rw-------    1 mail     mail         1496 Sep  1 00:11 bayes_msgcount
 -rw-------    1 mail     mail       118784 Sep  1 00:11 bayes_seen
 -rw-------    1 mail     mail      1327104 Sep  1 00:11 bayes_toks
 -rw-r--r--    1 mail     mail          741 Aug 21 01:20 user_prefs

I made these modifications:
 # addgroup --system  sa
 # adduser kenneth sa
 # adduser mail sa
 # chown -R mail:sa /var/mail/.spamassassin
 # chmod g+rwx /var/mail/.spamassassin
 # chmod 0664 /var/mail/.spamassassin/*

And sent myself a test message from my work account:
  X-Spam-Status: No, hits=-5.4 required=5.0
     tests=BAYES_01
     version=2.55 

So it seems to work.

In the end it might have been easier to just filter @ the Procmail
level, but I understand with Exim4 it's possible to reject mail @ the
SMTP level based on SA results.. which seems like a desirable thing to
implement when I finally get around to upgrading exim

If it's a half-baked approach, I'd appreciate any comments..

Thanks again,
Kenneth
