Normally, you mail it to a server which keeps an up-to-date list of
moderators, normally to moderators.isc.org which is an MX record pointing to
several sites which maintain a complete list of moderators worldwide.
 However, you will save one hop if you use usenet.org.uk for groups in uk.*,
and this is recommended.

In CNews, one of the following entries in your 'mailpaths' file should
suffice.

		--------------------------------
bionet		%s@net.bio.net
gnu		%s@tut.cis.ohio-state.edu
linux		submit-%s@ratatosk.yggdrasil.com
it		%s@news.nis.garr.it
nl		%s@nl.net
nz		%s@usenet.net.nz
uk		%s@usenet.org.uk
england.*	%s@england.news-admin.org
all		%s@moderators.isc.org
		--------------------------------

The entries for gnu.* and nz.* were taken from the "nz.* Usenet Hierarchy
FAQ". Entries for other top-level hierarchies would be welcomed.

The arrangements in INN are, as usual, similar but different. I believe the
following should work.

		--------------------------------
bionet.*:%s@net.bio.net
gnu.*:%s@tut.cis.ohio-state.edu
linux.*:submit-%s@ratatosk.yggdrasil.com
it.*:%s@news.nis.garr.it
nl.*:%s@nl.net
nz.*:%s@usenet.net.nz
uk.*:%s@usenet.org.uk
england.*:%s@england.news-admin.org
*:%s@moderators.isc.org
