SELinux is preventing /bin/mailx from 'read' accesses on the directory /var/spool/cron.

*****  Plugin leaks (50.5 confidence) suggests  ******************************

If you want to ignore mailx trying to read access the cron directory, because you believe it should not need this access.
Then you should report this as a bug.  
You can generate a local policy module to dontaudit this access.
Do
# grep /bin/mailx /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

*****  Plugin catchall (50.5 confidence) suggests  ***************************

If you believe that mailx should be allowed read access on the cron 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 mail /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
