#2366: Sync relay's policy with published descriptor.
---------------------+------------------------------------------------------
 Reporter:  postman  |        Type:  defect           
   Status:  new      |    Priority:  normal           
Milestone:           |   Component:  Tor Relay        
  Version:           |    Keywords:  dns reject policy
   Parent:           |  
---------------------+------------------------------------------------------
 If DNS is screwed up then an exit relay don't claim to be an exit. So it
 publishes descriptor with "reject star" policy. While it still behave like
 exit, it fetches extra stuff and etc. Relay's policy need to be synced
 with stuff used by clients.
