Hi
We are tring to move our mx server to another isp.
You have two postfix installations then, one in your current MX record
and a new
which is not yet published on DNS . Is that correct ?
They gave us an IP address but there is some strange points. When i
try to connect any mail related port on that ip, it send my connection
to our new postfix server. There is a destination nat on it. It is
strange becouse i can't see my actual source ip. I tried with many
different hosts and It looks like there is a source nat and i saw same
ip as my source ip wherever i try.
Are you talking about telnet to this IP to check if it works OR you're
trying to send SMTP ? if the later is the your case
then it works as it supposed to , your MX record is on your current
installation not the new one .
From new postfix server, when i try to reach any server on internet,
i see another ip address on the source ip field and it is fixed too.
I believe there is a mistake. Could it be feasible two different ip
for incoming and outgoing on one mx server ?
