Mark, this works for me with nmh. From my .mh_profile: Alternate-Mailboxes: ruben@rediris.es, ruben.martinez@rediris.es, ruben repl: -annotate -nocc me -cc to -cc cc (actually my line is longer with formats and filters, but you get the idea - the alternate mailboxes stuff is what (n)mh uses to decide which addresses qualify as 'me')
