Email notifications received repeatedly


We have many rules and many notifications by email, and they work perfectly in Arcsight 6.5.0.

But last days, we received daily one old mail. The same every day (and sometimes, more than one for day). I cannot see any event that say me why that mail is sended. And I cannot find any temporal file or log where find that mail and delete it.

Can you help me?
