I'll champion the cause of the ignorant. Just turn on ruf and "see" what comes 
in. It's a very effective way of figuring out what you are doing, and what 
effect your DMARC policy made. If you don't find the data useful, turn it off 
and route the reports to /dev/null.  

On that note, if one thought it possible that they'd get a very large quantity 
of reports, a compelling argument could be made for publishing separate email 
addresses for rua and ruf reports.  :-)
