Thank you for all you answers. SA is setup as a demon.
I have managed to "solve" this problem after turning on debug mode for bayes (-D bayes). I was able to correlate that 10% of my messages not scanned by bayes are connected with this error: bayes: no dbs present, cannot tie DB R/O: /var/spool/exim4/.spamassassin/bayes_toks I don't know why exim4 home directory is used. SA is running on user spamd with HOME=/home/spamassassin. The rest (90%) of messages are filtered just fine: bayes: tie-ing to DB file R/O /home/spamassassin/.spamassassin/bayes_toks bayes: tie-ing to DB file R/O /home/spamassassin/.spamassassin/bayes_seen SA is accepting messages only from remote mail system. SA arguments: /usr/local/bin/spamd --create-prefs -A ..... -i ....... -s mail --helper-home-dir -u spamd -d --pidfile=/var/run/spamd.pid --helper-home-dir - ? I have solved this problem by creating link /var/spool/exim4/.spamassassin -> /home/spamassassin/.spamassasin. I know it is ugly, but it works for me.
