Make your secondary mx aware of all the valid recipient addresses.Are there mechanisms in postfix or sendmail to do this automatically, or should this be done out-of-band? I've tried looking for this feature, but found nothing; maybe I don't know the right terms to search for.
Just about any MTA that is serious enough to be used also supports some kind of networked database for recipient lookups. With postfix, check the docs for local_recipient_maps. I don't remember how this is done in Sendmail, but it's possible there too. There can be a second step here, of separating the recipient lookups from the known (local) delivery mailboxes. Getting the lookups and the remote delivery to work together can be non-obvious and tricky. With postfix, check http://www.postfix.org/LDAP_README.html for a discussion on using virtual maps to make this work. -- Eric A.
