Description of problem:
starting postfix
SELinux is preventing /usr/libexec/postfix/smtpd from 'lock' accesses on the file /var/spool/postfix/pid/inet.smtp.

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

If vous pensez que smtpd devrait être autorisé à accéder lock sur inet.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 smtpd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
