There is probably some performance hit related to what else is
on the wire but not enough to matter.  It will end up having to
put the card in promiscuous mode and matching up the addresses
in software.  A switch port will have sorted it out for you
anyway.

What's going to happen to outbound mail being received on
some address as a relay that happens to be addressed to
a domain that you've MX'd and expect to receive on a
different address?  Or is this a 'receive-only' box?
