posting to foreign servers

[feren@ctron.com (Andrew C. Feren)]

	A friend of mine needs to be able to browse and post to a
	foreign server.  The browse part was easy, but gnus does not
	seem to want to post. 

	Basically what he wants to accomplish is to use one server for
	all but 1 or 2 groups which are only carried on the alternate
	server.

	Everytime we try to post an article we get the following error
	message.

Couldn't send message via news: 441 No such newsgroup as "ctron.test" 

	Posting to groups carried by the default server works fine.  I
	suppose he could start gnus using the alternate server as his
	default when he plans to post something, but that seems like
	the wrong way to approach the problem.

	I have, Gnus v5.3; nntp 4.0; nnml 1.0.  I think he has a
	version or two behind that, but that can be remedied easily
	enough.  So far we have played mostly with gnus-nntp-server
	and gnus-current-select-method.  Any other suggestions?
	
	Ideally he would like it set up so gnus "does the right
	thing".  Basically if he tries to post to a group that he
	reads from a foreign server gnus will attempt to post to the
	foreign server rather than the default server.
	
	Thanks in advance.
