Yes.  The scenario is this (I'll just review one direction here).  With
one gateway, the objective is to subscribe to the list and post items
you receive to the newsgroup, and submit newsgroup postings to the list.
Ideally you can 'recognize' your own items so it doesn't loop.

Currently there are two gateways, both are trying to echo list postings
to the newsgroup.  Joe's is doing a pretty good job, and as the
occasional articles arrive at American, it posts them back to the
newsgroup [Joe's doesn't post news to list yet, so we only have a half
loop].

As Listserv receives postings, "selected text" of the message body is
checksummed for use in duplicate detection as well as spam detection
(people posting slightly tailored articles to numerous lists).  This is
what caused the "duplicate posting rejected" notices I mentioned in a
previous Administrivia note.  However, Listserv only keeps a "cache" of
articles for 48 hours [I think].  If the American gateway had a lag of
over 48 hours, Listserv actually posted the duplicate as you observed
since it had been cleansed from the cache.
