We have a MDaemon email sevrer hosting in our office in Vietnam using lease line 1.5Mbps. Inside Vietnam, our staff can access email without any problem but in some countries like Australia, HongKong and especially in USA they can't send/receive there mails or if yes, it's very very slow. We plan to have a second server somewhere outside Vietnam to let staff working abroad can check their mail from this second mail sevrer. Please help us how to synchronize 2 servers, how to setup that staff working from abroad can accsess the second server. Or if you have another solution for us.
