Sure, but it might also "confuse" some mail servers.... I don't know. Guess some will sent to the lowest MX and not to any other mail server and will never get to you, but that would probably be rare.

My understanding is that only scripts used by spammers do that. I've never heard of such behaviour from a legitimate MTA - if there is one, it has such a small share of MTA installations that I think we can safely not care about it. I might be wrong, but I suspect that you have to try the secondaries in order to implement the RFCs properly.
