Discussion

If informational and more severe SMTP service messages are not logged, malicious activity on the system may go unnoticed.

Check Content

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

Procedure:
# grep "mail\." /etc/rsyslog.conf 

If syslog is not configured to log critical sendmail messages ("mail.crit" or "mail.*"), this is a finding.

Fix Text

Edit the syslog configuration file and add a configuration line specifying an appropriate destination for "mail.crit" syslogs.

For example:
mail.*             -/var/log/mail;RSYSLOG_TraditionalFileFormat
