[Dovecot] Double logging problem

Hi,

I have a relatively new installation with LDAP and Postfix, running smoothly on CentOS but it logs dovecot messages both in /var/log/messages and in /var/log/dovecot.log.

I have configured it to log in /var/log/dovecot.log (with syslog_facility: local1 and a respective line in syslog.conf, see below) but it also logs in /var/log/messages. As a result, I would expect it to only log into /var/log/dovecot.log.

Can someone suggest why this happens and help me stop logging dovecot messages in /var/log/messages ? Could it be because the following directive (in syslog.conf) does not capture dovecot messages to exclude them? *.info;mail.none;authpriv.none;cron.none
/var/log/messages

Could I use something like (in syslog.conf):

 *.info;mail.none;authpriv.none;cron.none;dovecot.none 
            /var/log/messages

to capture dovecot messages and *exclude* them from /var/log/messages ? I am not sure if syslog understands "dovecot.none". Please explain how this could be done.

Here is the configuration (I've changed real domain name with example.com):

# dovecot --version 1.2.11

# dovecot -n

# 1.2.11: /etc/dovecot.conf
# OS: Linux 2.6.18-194.3.1.el5.centos.plus x86_64 CentOS release 5.5

P.S. I sent this message earlier (a few hours ago), but I didn't see it coming in the dovecot list, so I've decided to send it again.
