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

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

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