Hi Rodrigo and thanks for your answer.

The problem is that for redundancy purposes, we have a replication at the storage level of the domino servers over a LAN2LAN, and we have high traffic , and thats why we want to put a third server in the branch office (that it is actually our contingency datacenter) to release the high traffic on the LAn2Lan and the replication can be performed over the MPLS (at domino level).

Make a restrictions to the other 2 servers doesn't like me. I can't find an scenario of branch offices for domino servers and how they work.

If i configure the Home Mail server in the Location Document to use the third server, you think it will work?
