Hi
From a certain time i have problem running up postfix. When i type from the console /etc/init.d/postfix startevery thing seams to be ok. But status command reports that postfix is down. I searched it up and found strange AVC Denied read messages.
I tried to relabel whole filesystem but whichout luck. When i stop SELINUX evertything is working.
Can somebody help me?
This is the message i get in audit.log
