Hi Brad --

Thanks for the reply.  My understanding is that Exim automagically finds the mailing lists without discrete entries in the alias file, and this in fact works for locally-generated postings.  That it works there, but fails for remote mail, is what's puzzling to me.

I'll wander off to the Exim groups to see what I find there.
