I am told to setup a free mail server on windows server in 2-3 days. I found hmailserver can be installed on windows. I went through http://www.hmailserver.com/documentation/v5.3/?page=basic_configuration
but getting confused on public host name?
server is inside the local network ie domain.local. hmailserver asks for public host name on which mail server is installed, but my server i not hosted or its server.domain.local
Can someone help me setup mail server inside office but it should send\receive mail globally? As i have never setup mail server before kindly guide how to do dns entry for mx record etc.,
