    Default [SOLVED] Distribution of my band width

    Hi guys i got a single box zimbra implementation with zimbra nw 5.0.5 on a centos 5, my custumer says that he want's to have two channels for mail transport, one should be used for internal mail, so any address with domain custumer.com should go for channel 1 and all external mail should use channel 2, is there a way to acomplish it? maybe installing another mta zimbra box, rember that i got a single server not multi server implementation (they are just 70 users :s ) thanks any help

    what do you mean by 'channels'? If you have 2 separate network interfaces, then you could accomplish this probably by adding a routing statement saying that net ip address of customer1's server is reachable via interface1 and customer2's server is reachable by interface2

    Zimbra will make all services available on all interfaces. It is the client that needs to be pointed to the correct interface. I use DNS to accomplish this. An internal DNS server for resolving on my LAN and my registered name servers for WAN name resolution.

    Depending on how many local pc's you have on the LAN, instead of a local DNS server you can add the LAN IP of the mail server to the HOSTS file on the Client PC's. This will work just as well. By default, a PC will look at the HOSTS file for name resolution before querying a DNS server.

    You could also achieve this on a single NIC using Linux Advanced Routing and Traffic Control
