Description of problem:
I don't know what happened, I just use Kmail with my gmail account
SELinux is preventing /usr/bin/procmail from 'read' accesses on the file unix.

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

If cree que de manera predeterminada, procmail debería permitir acceso read sobre  unix 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 procmail /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
