    I have a Windows 2003 Server running IPswitch IMail in our small office. We
    have a business class DSL with dial-backup and I have a DNS question I am
    hopeing someone can answer. We have a static block of 5 Static IP's routed to
    us and the issue is that we host e-mail for our small business customers (we
    provide consultin g services) and the issue is that I want to provide proper
    RDNS for the domains we host. Now here is the question, what is the proper
    way to provide RDNS for virtual hosted services in Windows? Usually we would
    ask our upstream ISP to host DNS for the domains and then provide for RDNS
    for a specific IP to domain but they don't usually allow for multiple RDNS
    entries per IP. So how can I make sure that lets say X.X.X.33 resolves to
    host.domain.com for lets say 4-10 domains? I am not sure I am phrasing this
    right but essentially I want to host the e-mail domains on a single server,
    then provide rdns for spam reasons for the ip's assigned to us. Should I A.
    ask to be delgated authority over the DNS for the netblock or B. create some
    kind of master domain that everyone would send mail thru? I know this is a
    common problem I just don't know how to solve it.
