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.
