Anyone knows if it is possible to configure a load balancing of two C100 in a cluster. I configured the second machine in the cluster two weeks ago. when I look in the stats, the second machine does nothing. the first machine is on 3% CPU and whe have about 120000 mail per day.
is there any way to configure the cluster that the two machine share their work ? or is the cluster only for fail-safe ?
Most mail admins know how to use MX records for load balancing (and redundancy) on their mail servers. Less people know you can use MX also for your outgoing mail traffic.
Just add a MX record to your local DNS and specify a name for the record. (i.e. outgoingMX.local.domain) put the IP's or hostnames of your internal Ironport card in the data and configure your internal mail system to deliver it’s outgoing mail to smarthost outgoingMX.local.domain Works for most mail systems. I'm sure it is working for Exchange (5.5. and higher) and Domino (5 and higher)
