Hi Robert

yes, I've just tried that, but it made no difference.  I've been reading
a bit, and I think the issue is that postfix adds X-Original-To when
delivering to a mailbox - which delivery via smtp/lmtp isn't. 

I'm not sure if postfix should be adding it - postfix applies
virtual_aliases_maps, then delivers to dovecot via lmtp (set up via
virtual_transport) - without X-Original-To, the information
of "original recipient" is lost at this point.
