At least if you do, it's very helpful if the two sites have identical
policies with regards to such things as relaying, checking envelope
sender domains and the like. And it's a lot better if the primary MX
does like qmail and accepts mail even for non-existing users, or else
the secondary MX gets saddled with creating bounce messages on behalf
of the other domain. And that is bad indeed. Been there, done that,
got the T-shirt.
