Per user blacklist

[Jay Hall <jh...@vandaliamo.net>]

I have setup SpamAssassin 2.64, and qmail-scanner 1.23 on FreeBSD with 
perl-5.8.4 and have been using them separately with great success. 
However, I have decided to use qmail-scanners ability to run 
SpamAssassin as the mail is processed.  And, I have this working to a 
point (i.e. the mail is flagged correctly accoring to rules), but I 
cannot get the blacklist to be recongized.

Spamd is running as root.  Spamc is called from the 
qmail-scanner-queue.pl script with -u qscand.  qscand is the user whose 
rules I would like to have used.  In debug, I see the following

logmsg: handle_user: unable to find user 'jay.hall@mnea.org'!
logmsg: Still running as root: user not specified with -u, not found, or 
set to root.  Fall back to nobody.

I understand not being able to find the user jay.hall@mnea.org since 
this server is simply a relay for scanning, etc. before the e-mail is 
delivered to the Exchange server.  My thinking was that with the -u 
option whenever a user is not found, the rules in the 
/home/qscand/.spamassassin directory would be used.  The other thing 
that is puzzling is that I have added, for testing purposes, my e-mail 
address to the blacklist for nobody, and once the e-mail is received, I 
am not being identified as a blacklisted sender.  If I add the blacklist 
entry to local.cf, I am properly identified as a blacklisted send.

How do I force SpamAssassin to use a particular user's rules, as opposed 
to nobody, when the user is not found?

Any ideas what I might be doing wrong with the blacklists?

Thanks for all your help.
