Hi Zhang,

I have 5 IPs on the server and need to change the IP output of the emails. I can not change the main server IP (eth0) for reasons of infrastructure. I tried the parameter "inet_interfaces" in main.cf but still leaving the main server IP to output of the email.

There is another way?

Re: Change output IP

You can do it with iptables rules to mark SMTP outgoing traffic and redirect output with specific IP.


Re: Change output IP

Did you try Postfix setting "smtp_bind_address"?
