Odd, it looks like network tests *should* be running...

Also: your bayes database files will probably be under popuser's home
directory. See anything there?

CentOS is RHEL-based, right? Likely /etc/rc.d/init,d/spamassassin

You may be able to check this using "ps -fax" to see what the
currently-running SA instance has for its command line.

cd /var/qmail/mailnames/blah.com/mark/.spamassassin
[root@condor .spamassassin]# ls
total 1691
   1 ./     1 ../   408 auto-whitelist    97 bayes_journal   141 bayes_seen  1042 bayes_toks     1 user_prefs

This auto-whitelist file looks very suspicious.  It is filled with spammer addresses... the mark@ addresses I was talking about.

You'll also want to look in /etc/sysconfig/spamassassin

Just contains:

SPAMDOPTIONS="-d -c -H --max-children=1"


I have decided to restart this whole process... setting the bayes
database back to its initial state & deleting auto-whitelist file.

Is it good to use a bayes starter DB ?  If so, where can I get
a good one.

thanks,
JC

It's not generally a good idea to use *somebody else's* data for your
starter DB - the nature of their email traffic is not likely to be
similar to yours.

This is why it's a good idea to keep the messages you use to train
your bayes, if you're doing manual training - so that you can correct
training errors, and retrain from scratch if necessary. Of course,
that doesn't scale too well if you have large numbers of users and are
autolearning...

If your users retrieve their email from your server using IMAP, here's
one thing you can do: set up a SpamAssassin-SPAM and SpamAssassin-HAM
mail folder in each user's mailbox. Have them move missed spams to the
SpamAssassin-SPAM folder, and *copy* false positives (SA says it's
spam when it isn't) to the SpamAssassin-HAM folder. They can (and
ideally *should*) also copy some legitimate messages to their
SpamAssassin-HAM folder so that SA can get an idea of what "ham" looks
like.

You can then train off those folders, and retrain as needed. To manage
the training work, you can rotate those files on a schedule - e.g. on
October 1, everybody's SpamAssassin-HAM becomes
SpamAssassin-HAM-200709, etc.

I have some scripting for that sort of thing here:
