Email going to two servers depending on the alias

[dmurfitt]

Hi,

Does anyone know of a way to make email go to one server (MX record) for some email aliases, and to another for others aliases? Basically we have two sites with the same email domain, and they are both running exchange. But some users are at one site, and others are at the other site. It's a bit confusing, but I'm sure it's possible.

Any ideas?

Thanks,
