Description Michael S. 2013-05-04 20:00:14 UTC
Description of problem:
I was trying to run mailq on my laptop, with postfix running
SELinux is preventing /usr/libexec/postfix/showq from read, write access on the file /var/spool/postfix/pid/unix.showq.

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

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

Comment 1 Michael S. 2013-05-04 20:23:22 UTC
Also, it need others access than read and write, as seen by further observation :
getattr, lock
