If Sendmail is not configured to log at level 9, system logs may not contain the information necessary for tracking unauthorized use of the sendmail service.

Check Content

If the “sendmail” package is not installed, this is not applicable.

Check if the sendmail package is installed:
# rpm –q sendmail
If it is installed, the logging level must be set to level nine:

Procedure:
for sendmail:
# grep "O L" /etc/mail/sendmail.cf

OR

# grep LogLevel /etc/mail/sendmail.cf

If logging is set to less than nine, this is a finding.

for Postfix:
This rule is not applicable to postfix which does not use "log levels" in the same fashion as sendmail.
