Discussion

The "sendmail "software was not developed with security in mind, and its design prevents it from being effectively contained by SELinux. Postfix must be used instead.

Check Content

Verify the "sendmail" package is not installed using the following command:

$ sudo dnf list --installed sendmail

Error: No matching Packages to list

If the "sendmail" package is installed, this is a finding.

Fix Text

Remove the "sendmail" package using the following command:

$ sudo dnf remove sendmail
