Comment (by oc):

 I've just discovered the `ServerDNSSearchDomains` config flag:
 {{{
 ServerDNSSearchDomains 0|1
     If set to 1, then we will search for addresses in the local search
 domain.
     For example, if this system is configured to believe it is in
 "example.com",
     and a client tries to connect to "www", the client will be connected
 to
     "www.example.com". This option only affects name lookups that your
 server
     does on behalf of clients. (Default: 0)
 }}}
 If set, the exit relay might receive non-FQDN requests. Therefore the
 client should be able to send them: TLD syntax cannot be used to validate
 requests.
