SELinux is preventing systemd from 'search' accesses on the directory /var/spool/postfix.

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

If you believe that systemd should be allowed search access on the postfix directory 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:
# grep systemd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
