address

Is that possible to bind all available public ip addresses on a server to one Postfix instance as its outgoing ip pool and let it choose a random ip or specified ip from the pool each time it sends out an email?

If above is not possible, can it be configured to listen on one public ip address per instance and each time it delivers a message, it use the binded one as outgoing ip address.
