DOMAIN(8)
NAME
  domain - nnrpd domain resolver

SYNOPSIS
  domain domainname

DESCRIPTION
  This program can be used in readers.conf to grant access based on the
  subdomain part of the remote hostname.  In particular, it only returns
  success if the remote hostname ends in domainname.  (A leading dot on
  domainname is optional; even without it, the argument must match on dot-
  separated boundaries).  The "username" returned is whatever initial part of
  the remote hostname remains after domainname is removed.  It is an error if
  there is no initial part (that is, if the remote hostname is exactly the
  specified domainname).

EXAMPLE
  The following readers.conf(5) fragment grants access to hosts with internal
  domain names:

      auth internal {
	  res: "domain .internal"
	  default-domain: "example.com"
      }

      access internal {
	  users: "*@example.com"
	  newsgroups: example.*
      }

  Access is granted to the example.* groups for all connections from hosts
  that resolve to hostnames ending in ".internal"; a connection from
  "foo.internal" would match access groups as "foo@example.com".

BUGS
  It seems the code does not confirm that the matching part is actually at
  the end of the remote hostname (e.g., "domain: example.com" would match the
  remote host "foo.example.com.org" by ignoring the trailing ".org" part).

  Does this resolver actually provide any useful functionality not available
  by using wildcards in the readers.conf(5) hosts parameter?  If so, the
  example above should reflect this functionality.
