Ensure access to /var/spool/clientmqueue is configured

MediaNivel 1Automatizadaaix

Descripción

The recommended DAC (discretionary access control) settings for the /var/spool/clientmqueue directory are applied. Queued messages are the messages that have not yet reached their final destination. To ensure the integrity of the messages during storage, the mail queue directory must be secured from unauthorized access. Audit: compares `ls -ld` mode (this mode or more restrictive), owner and group with the CIS values; ACLs are not evaluated.
