Just did a basic install of postfix on a U10.04LTS server. Reading over the manual and playing a bit, but the problem is this server will be one of 5 behind a load balancer (for other things).
Mail will only be outbound, and currently when the mail is sent from the 1st box which is running the header shows; Received: from mail.domain.com ([1.2.3.4]) Now the 1.2.3.4 IP is that of the loadbalancer (the outbound gateway for the server). The LB is on a /29 so I want to allocate a seperate virtual IP 1.2.3.5 for example which will have a virtual service set to pass that ip's traffic to that mail server. I tried to issue an smtp_bind_address = 1.2.3.5 and got the following error; *warning: smtp_connect_addr: bind 1.2.3.5: Cannot assign requested address*which I assume it's because that local box doesn't have that IP. So with all the above info, I just need to see how when the mail get's sent, the received from has the [1.2.3.5] IP as opposed to the other. Thanks.
