SELinux is preventing /usr/sbin/exim from 'append' accesses on the file /var/lib/rkhunter/rkhcronlog.WxzHJfwUYD.

*****  Plugin restorecon (98.5 confidence) suggests  *************************

If you want to fix the label. 
/var/lib/rkhunter/rkhcronlog.WxzHJfwUYD default label should be var_lib_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /var/lib/rkhunter/rkhcronlog.WxzHJfwUYD

*****  Plugin catchall (1.48 confidence) suggests  ***************************

If you believe that exim should be allowed append access on the rkhcronlog.WxzHJfwUYD 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:
# grep sendmail /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

*****  Plugin leaks (1.48 confidence) suggests  ******************************

If you want to ignore exim trying to append access the rkhcronlog.WxzHJfwUYD file, 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 /usr/sbin/exim /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp
