SV-50472r1_rule The sendmail package must be removed.

Vulnerability discussion

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

Check content

Run the following command to determine if the "sendmail" package is installed: # rpm -q sendmail If the package is installed, this is a finding.

Fix text

Sendmail is not the default mail transfer agent and is not installed by default. The "sendmail" package can be removed with the following command: # yum erase sendmail

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
