handle_user unable to find user

[Dan Horne <da...@taisweb.net>]

Setting up a new mailserver on FreeBSD 5.4 using postfix and maildrop
which calls spamc.  So far it is working like this: All users are
virtual and need per-user filtering. Postfix and maildrop get user
information from a mysql db, so once postfix passes the email to
maildrop:

1) maildrop calls spamc with the following line in maildroprc:

exception {
   xfilter "/usr/local/bin/spamc -u $LOGNAME "
}

2) /usr/local/etc/rc.d/sa-spamd.sh (the FreeBSD startup script for
spamd) has the following line:

spamd_flags=${spamd_flags:-"-c -d -r ${spamd_pidfile}
--virtual-config-dir=/home/vmail/%d/%l/.spamassassin "}


When sending an email I get the following in the logs:

spamd: handle_user unable to find user: validuser@example.com
spamd: still running as root: user not specified with -u, not found, or
set to root, falling back to nobody at /usr/local/bin/spamd line 1147,
<GEN10> line 4.

So, if I am reading this right, maildrop is passing the correct user via
the -u switch (validuser@example.com), so spamd should try to get its
settings from /home/vmail/example.com/validuser/.spamassassin.  However,
for some reason it is not able to do so.  

Basically I need per-user settings running spamd with only virtual users
on the box, and the method of doing that is not as important as the end
result.  So if there is a BETTER way of running spamc with per-user
settings in my config, please let me know.  Otherwise, can someone help
me understand why I am getting the message "handle_user unable to find
user: validuser@example.com" in the logs?  

Thanks,

Dan Horne

You might take a look at the docs at 
http://perlstalker.amigo.net/tiki/tiki-index.php?page=CourierSpamAssassin. It 
may not all apply to you but it should give you an idea.

 It looks to me like you don't have per-user settings in your mysql db for
that particular user. I do domain-based settings so I always get that
message in my logs. It will say that if there are no rows in the db with
that user's email address, and is normal.

However, the spamd as root thing is a separate issue.
