The replication strategy for this company would be to implement a Mirrored Configuration between the three sites. Each site should schedule an e-mail replication with the other two sites at a pre-determined time every day. For example, at 8:00pm Site A would schedule an e-mail replication to Site B and Site C. At the same time Site B would schedule an e-mail replication with Site A and Site C. Similarly, Site C would schedule an e-mail replication with Site A and Site B. Each Site would send the resulting e-mail commands and should each then connect an hour or so later in order to receive the changes from the other sites.
