Description of problem:
SELinux is preventing /usr/sbin/postqueue from 'block_suspend' accesses on the capability2 .

*****  Plugin catchall (100. confidence) suggests  ***************************

If vous pensez que postqueue devrait être autorisé à accéder block_suspend sur  capability2 par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
Do
autoriser cet accès pour le moment en exécutant :
# grep postqueue /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
