Greetings.
I'm working on creating a system-wide SpamAssassin installation with
virtual users, using Postfix on the front-end and dbmail on the
back-end. I have a few questions regarding this.
With regard to Bayes filtering, I've copied my old, personal Bayes
databases over to a global Bayes store, in order to use these databases
as a "seed" for the system-wide filter. This seems to work (though, I
haven't done extensive analysis to determine whether it really is a good
thing to do), but I'm concerned about bayes_journal being deleted when I
run sa-learn.
Viz.:
^ [EMAIL PROTECTED]:/srv/disk_pony/bayes_store$ ls -l
total 46352
-rw-rw---- 1 dbmail staff 56088 2008-05-04 19:08 bayes_journal
-rw-rw---- 1 dbmail staff 41824256 2008-05-04 18:53 bayes_seen
-rw-rw---- 1 dbmail staff 5521408 2008-05-04 18:53 bayes_toks
^ [EMAIL PROTECTED]:/srv/disk_pony/bayes_store$ ls -l
total 46296
-rw-rw-rw- 1 dbmail staff 30 2008-05-04 19:56 bayes.mutex
-rw-rw---- 1 dbmail staff 41824256 2008-05-04 19:56 bayes_seen
-rw-rw---- 1 dbmail staff 5521408 2008-05-04 19:56 bayes_toks
Between those `ls -l` runs, I ran the following in a separate terminal.
This ~/bayes_learn directory just contains a bunch of hammy mailing
list messages that I'm using to test the system.
^ [EMAIL PROTECTED]:~/bayes_learn$ sudo -u dbmail sa-learn --ham
1209916419.26777_1.iron:2,
Learned tokens from 1 message(s) (1 message(s) examined)
So, during sa-learn, the bayes_journal is deleted, and a new bayes.mutex
shows up. What is the significance of this?
I'm not sure what the bayes_journal contains, but I know it grows when
SpamAssassin processes an email. Its summary deletion during the
sa-learn process bothers me.
I'd appreciate any comments or observations you may have. :)
This is SpamAssassin version 3.2.4 running on Perl version 5.8.8, from
their respective Debian packages.
Other possibly relevant stuff follows.
spamd starts with "--max-children 5 --helper-home-dir -l".
/etc/spamassassin/local.cf contains, among other things:
bayes_path /srv/disk_pony/bayes_store/bayes
bayes_file_mode 0666
Thanks.
