Being a mail administrator for both work, and a couple of other sites, the only concern I would have with this is that you need to be fairly careful that the outgoing is routing out a machine that is authorized to send mail for these domains, otherwise, you'll be looking at a lot of providers blocking your messages as being potential spam fodder and subsequently blacklisting you or the domains in question.
