There are several hops that could randomize ips:

If you are only
interested in what mail clients do, and can't find any
online explanation, you could either look at the source
code to some open source ones (probably the easiest
way),
to me, this feels rather the most troublesome way :-)

Well, your configuration settings *are* for port 25. So testing

In my case, postfix-in and postfix-out is one instance.

Hi all,
I need create server with 5 IP addresses (interfaces) and postfix(es). The
role of this server is relay.
If message delivered into my mail server on one ip address, for example,
