In postfix, I'm calling spamassassin with the 2 lines:
smtp inet n - n - - smtpd -o
content_filter=spamassassin
spamassassin unix - n n - - pipe flags=R user=spamd
argv=/usr/bin/spamc -e /usr/sbin/sendmail -oi -f ${sender} ${recipient}
In /etc/cron.d/sa-learn I have:
51 * * * * spamd sa-learn --spam /var/log/spamassassin/SPAM/ >/dev/null 2>&1
52 * * * * spamd sa-learn --ham /var/log/spamassassin/HAM/ >/dev/null 2>&1
(/var/log/spamassassin is spamd's home directory, and it's where the SPAM/HAM
is getting copied for learning)
My /etc/mail/spamassassin/local.cf file is:
required_hits 5
report_safe 0
rewrite_header Subject [SPAM]
required_score 5.0
use_bayes 1
use_bayes_rules 1
bayes_auto_learn 0
bayes_path /var/log/spamassassin/.spamassassin/bayes
Would the above config make spamassassin run as the spamd user? (It's CentOS
6.5) I've verified the Bayes database is good and populated for user spamd.
Thanks,
Nick

So...
1) The Bayes DB for spamd has enough ham and spam to be used
2) Incoming email does not get a Bayes result
This means that the SA process scanning your mail is NOT using the same
database you are querying. The most common cause of this is running sa-learn
as the wrong user. Are you 100% sure spamd is running as the spamd user? It
may also be possible for config options or run-time flags to affect which
database is being used. Double-check your config and the options you are
passing to spamd.
