I'm running F24 so it's not straightforward to say what to do for F22. 
Do you have the mlocate package installed?  On F24:
    [mcallman@draco etc]$ rpm -q mlocate
    mlocate-0.26-14.fc24.x86_64

I don't think anacron or cron by themselves send mail unless a job
they're running sends output to STDOUT or STDERR.  Anacron/cron won't
send me a daily logwatch report -- that's configured in logwatch. 
Anacron just runs the job. You might also need to have something such as
sendmail installed that will do the mail delivery work. There was
something in recent release notes about not needing sendmail any longer
but I don't remember the details.

/etc/crontab should be empty.  The crond.service I believe runs what
users set up in their respective crontab files, what's in /etc/crontab
and also what's in /etc/cron.d.  The file "0hourly" in /etc/cron.d has
an entry to run each hour what's in /etc/cron.hourly. That has the file
"0anacron" which has some checks in it and then runs anacron, which then
runs everything listed in anacrontab.  Look at "0anacron" and you'll see
checks for /etc/cron.daily.  These checks might prevent daily jobs being
run twice if /etc/cron.daily is listed in both anacrontab and crontab
but it looks like it's an error to list /etc/cron.daily in both.  Same
for /etc/cron.weekly and the others.
