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: frommail.domain.com <http://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.
That header is added by the receiving server, not by your
postfix, and reflects the IP the receiving server sees.
Sounds as if you need to set your LB to always use a specific
address for outbound connections from that particular host.
This isn't a postfix config issue.
