[Dspam-user] "Unable to attach DSPAM context"; points to variation of mail/dspam directories, with "/local/" injected.

John Smith
I use dspam 3.10.1, dovecot 2.1.7, and postfix 2.9.6 on Debian 7.

When I run dspam_stats without "-H [hidden email]" or when
dspam_clean runs, it returns "Unable to attach DSPAM context" and
points to a variation of the mail/dspam directories, with "/local/""
injected, as below:

Mar 27 00:00:01 mars /USR/SBIN/CRON[7479]: (dspam) CMD (
/usr/bin/dspam_logrotate -a 30 -d /var/decrypted-mail/dspam/data/)
Mar 27 00:00:01 mars /USR/SBIN/CRON[7480]: (dspam) CMD (
/usr/bin/dspam_clean -s -p -u)
Mar 27 00:00:01 mars dspam[7482]: Unable to open file for writing:
/var/decrypted-mail/dspam/data/local/john/john.lock: No such file or
Mar 27 00:00:01 mars dspam[7482]: unable to attach dspam context

This is from the email dspam sends warning of the problem:
From: [hidden email] (Cron Daemon)
To: [hidden email]
Subject: Cron <dspam@mars>   /usr/bin/dspam_clean -s -p -u

Unable to attach DSPAM context
dspam_clean starting

I only use virtual mailboxes and domains for both local linux uses and
virtual mail users. These are via mapped mailboxes, domains, and alias
in postfix and with authentication via dovecot. For example, "john" is
a local linux account and that same user is "[hidden email]", via
virtual mail hosting.

domain.com  OK

[hidden email]   [hidden email]

[hidden email]   domain/john

[hidden email]:{CRAM-MD5}::snipped_for_space:5000:5000

mail_location = maildir:~/mail
mail_home = /var/decrypted-mail/vhosts/%d/%n

Home /var/decrypted-mail/dspam

Where could it be picking up
/var/decrypted-mail/dspam/data/local/john/john.lock from? How can I
verify if it is processing [hidden email]'s virtual mailbox, too?
There doesn't seem to be any verbose switch on dspam_clean.

Other than this, it generally seems to work. Mail arrives with the
headers including a list of tags and scores and a spam/not-spam
determination (though [SPAM] is not appearing in subject line even
though set in the config) and it seems to train it when I move mail
into and out of the Junk folder...

Any guidance would be appreciated. I've seen some other discussion
elsewhere about user being searched for in /local/data/, but they've
either been inconclusive or seem not quite related to what I'm seeing
or my setup.

I did read a post from two years ago on this list that stated the
following for a similar incident:

"The data/local/username construct is used if you have a setup that
requires usernames formatted as email addresses (you have that) but
you use a login name without a domain. Dspam then uses the 'local'
string in stead of the domain you failed to use."

Of course, as demonstrated above, mail users are only virtual and only
use [hidden email] to login. I suppose I should also ask -- where
does dspam even figure out the list of users to run dspam_clean or
dspam_stats against (if a user isn't provided on the command line), in
the first place, if it isn't just looking in the Home directory
provided in the dspam.conf?

I sincerely appreciate your time and input. Thank you. I'll include my
dspam.conf, below, because I'm not sure if doing it by pastebin is
accepted around here and I'd rather give you the information now than
waste your time asking me for it later.
