Description Wolfgang Rupprecht 2016-10-12 06:39:45 UTC 
Description of problem:
happened during normal postfix operation
SELinux is preventing postfix from 'read' accesses on the lnk_file log.

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

If you believe that postfix should be allowed read access on the log lnk_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'postfix' --raw | audit2allow -M my-postfix
# semodule -X 300 -i my-postfix.pp

Comment 2 Paul W. Frields 2016-11-07 14:58:36 UTC 
Description of problem:
It looks like this might be from postfix qmgr trying to read within its systemd-private folder in /tmp (i.e. /tmp/systemd-private-{hash}-postfix.service-{hash2}/tmp/).
