Description dan 2021-03-25 13:01:51 UTC
Description of problem:
SELinux is preventing postgrey from 'read' accesses on the file unix.

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

If you believe that postgrey should be allowed read access on the unix 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 'postgrey' --raw | audit2allow -M my-postgrey
# semodule -X 300 -i my-postgrey.pp
