Description of problem:
SELinux is preventing /usr/libexec/postfix/cleanup from using the 'execstack' accesses on a process.

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

If vous pensez que cleanup devrait être autorisé à accéder execstack sur les processus étiquetés postfix_cleanup_t 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 cleanup /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
