Depending on the size of the organization, the typical configuration is that the 2 systems you describe act only as "front-ends" accepting email from the Internet and generally acting as the gateways for internal systems sending emails out to the Internet. These 2 systems would then redistribute incoming emails to multiple smaller systems or a single system internally. Now, that is not to say you can't have multiple servers acting on the same "message store". I have done that, with varying degrees of success, with commercial SW using NFS mounted message store. I've not tried it with open-source SW.
