[Mimedefang] how to remove milter messages from the log?

[Gary Funck]

(disclosure: I'm a syslog novice)

I'm finding the following sorts of log entries to be not useful/needed:

Jan 12 16:55:37 intrepid sendmail[10286]: j0D0tWUD010286: Milter change:
header Content-Type: from text/plain; charset=us-ascii to text/plain;
charset=us-ascii
Jan 12 16:55:37 intrepid sendmail[10286]: j0D0tWUD010286: Milter change:
header MIME-Version: from 1.0 to 1.0
Jan 12 16:55:37 intrepid sendmail[10286]: j0D0tWUD010286: Milter change:
header Content-Transfer-Encoding: from 7bit to 7bit
Jan 12 16:55:37 intrepid sendmail[10286]: j0D0tWUD010286: Milter message:
body replaced
Jan 12 16:55:37 intrepid sendmail[10286]: j0D0tWUD010286: Milter add:
header: X-Scanned-By: MIMEDefang 2.49 on 192.195.190.1

Is there a simple way to keep those sorts of milter-related log entries from
being genearated?

Is this the only log-related control in sendmail?

dnl #
dnl # default logging level is 9, you might want to set it higher to
dnl # debug the configuration
dnl #
dnl define(`confLOG_LEVEL', `9')dnl

would moving it lower eliminate the milter messages?
