I used to use rec.aquaria at pubnews_demon.co.uk (just put the newsgroup name
in front of the @, whichever you want to post to), but I haven't used it in
a while.  I don't know if it's still good.  Does anyone know of another
reliable mail-to-news converter (preferably in the US)?  These converters
come and go all the time.
