Check the syslog configuration file for mail.crit logging configuration.

Procedure:
# more /etc/syslog.conf

mail.crit /var/adm/messages
*.crit /var/log/messages

Less severe syslog levels (err, warning, info, and debug) may be substituted for crit, since they will also capture crit level syslog messages. If syslog is not configured to log critical Sendmail messages, this is a finding.
