How to make Postfix use new IP address?

[stimpack]

I'm using the Postfix mail server and I have 2 IPs available. I'd like that my postfix can access to my others ips

How can I do this?

For example: main IP: 66.66.66.66 other IP: 66.66.66.67

The init_interfaces config setting identifies network interfaces:
http://www.postfix.org/postconf.5.html#inet_interfaces

You can check your current config via command line:

postconf inet_interfaces

Try adding

smtp_bind_address = 88.88.88.88

to your /etc/postfix/main.cf
