Fix Recommendation

Remove the extended ACL from the files.
# chmod A- /etc/mail/aliases /etc/mail/aliases.db

Check Contents

Find the alias files on the system.

Procedure:
# egrep '^O(A| AliasFile)' /etc/mail/sendmail.cf

If the "alias file" is an NIS or LDAP map, this check is not applicable. The default location is /etc/mail/aliases.

Check the permissions of the alias file and the hashed version of it used by sendmail.

Procedure:
# ls -lL /etc/mail/aliases /etc/mail/aliases.db

If the permissions include a "+", the file has an extended ACL and this is a finding.
