Check Text (C-215344r991589_chk)
Check if "Sendmail" logging is set to level "9" by running command:
# grep "^O LogLevel" /etc/mail/sendmail.cf
O LogLevel=9
If logging is set to less than "9", this is a finding.
Fix Text (F-16540r294484_fix)
Edit /etc/mail/sendmail.cf file, locate the "O LogLevel" line, or add a new line if necessary, and change the log level to "9". The new LogLevel line should be:
O LogLevel=9
