I gateway half-a-dozen or so mailing lists into usenet and back for
local reading.
 
What I do is:
 
(1) have the mail->news gateway insert an identifiable path component into
the path, and put !component in the newsfeeds (or sys-file, I did it with
C-News too) file to avoid it being sent out by the news->mail gateway.
 
(2) rather than passing it through inews, I pass the incoming article to
'rnews', which just logs it if it's a duplicate.  I get duplicates on
a regular basis (I carry both [log in to unmask] and [log in to unmask]
as mailing lists, and at least one person regularly sends mail to both
lists with the same message-ID).  This worked with both C-News and INN.
 
(3) I set the "envelope" of outgoing news->mail posts to be news@news...
so that bounces and the like wind up in my mailbox, not going back to
usenet or the list.
 
(4) for "Revised Listserv" lists, I tell LISTSERV to "set header ietf".
I know "proper" interpretation of the RFC's is a religious issue, but
doing this doesn't break any software or introduce unwanted headers.
 
Your mileage may vary, but I don't get problems with mailing-list loops
(knock on wood).
