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

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

If cree que de manera predeterminada, cleanup debería permitir acceso read write sobre  unix.cleanup file.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
permita el acceso momentáneamente executando:
# grep cleanup /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
