Description of problem:
SELinux is preventing /usr/libexec/postfix/smtp from read, write access on the file /var/spool/postfix/pid/unix.smtp.

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

If vous pensez que smtp devrait être autorisé à accéder read write sur unix.smtp file 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 smtp /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
